The bitter events brought about by blind terrorism in France have once again, moved me to speak to you young people. In the Name of God, the Beneficent, the Merciful To the Youth in Western Countries, The bitter events brought about by blind terrorism in France have once again, moved me to speak to you young people. For me, it is unfortunate that such incidents would have to create the framework for a conversation, however the truth is that if painful matters do not create the grounds for finding solutions and mutual consultation, then the damage caused will be multiplied. The pain of any human being anywhere in the world causes sorrow for a fellow human being. The sight of a child losing his life in the presence of his loved ones, a mother whose joy for her family turns into mourning, a husband who is rushing the lifeless body of his spouse to some place and the spectator who does not know whether he will be seeing the final scene of life- these are scenes that rouse the emotions and feelings of any human being. Anyone who has benefited from affection and humanity is affected and disturbed by witnessing these scenes- whether it occurs in France or in Palestine or Iraq or Lebanon or Syria. Without a doubt, the one-and-a-half billion Muslims also have these feelings and abhor and are revolted by the perpetrators and those responsible for these calamities. The issue, however, is that if today’s pain is not used to build a better and safer future, then it will just turn into bitter and fruitless memories. I genuinely believe that it is only you youth who by learning the lessons of today’s hardship, have the power to discover new means for building the future and who can be barriers in the misguided path that has brought the west to its current impasse. “ Anyone who has benefited from affection and humanity is affected and disturbed by witnessing these scenes- whether it occurs in France or in Palestine or Iraq or Lebanon or Syria. It is correct that today terrorism is our common worry. However it is necessary for you to know that the insecurity and strain that you experienced during the recent events, differs from the pain that the people of Iraq, Yemen, Syria and Afghanistan have been experiencing for many years, in two significant ways. First, the Islamic world has been the victim of terror and brutality to a larger extent territorially, to greater amount quantitatively and for a longer period in terms of time. Second, that unfortunately this violence has been supported by certain great powers through various methods and effective means. Today, there are very few people who are uninformed about the role of the United States of America in creating, nurturing and arming al-Qaeda, the Taliban and their inauspicious successors. Besides this direct support, the overt and well-known supporters of takfiri terrorism- despite having the most backward political systems- are standing arrayed as allies of the west while the most pioneering, brightest and most dynamic democrats in the region are suppressed mercilessly. The prejudiced response of the west to the awakening movement in the Islamic world is an illustrative example of the contradictory western policies. “ I genuinely believe that it is only you youth who by learning the lessons of today’s hardship can be barriers in the misguided path that has brought the west to its current impasse. The other side of these contradictory policies is seen in supporting the state terrorism of Israel. The oppressed people of Palestine have experienced the worst kind of terrorism for the last sixty years. If the people of Europe have now taken refuge in their homes for a few days and refrain from being present in busy places- it is decades that a Palestinian family is not secure even in its own home from the Zionist regime’s death and destruction machinery. What kind of atrocious violence today is comparable to that of the settlement constructions of the Zionists regime? This regime- without ever being seriously and significantly censured by its influential allies or even by the so-called independent international organizations- everyday demolishes the homes of Palestinians and destroys their orchards and farms. This is done without even giving them time to gather their belongings or agricultural products and usually it is done in front of the terrified and tear-filled eyes of women and children who witness the brutal beatings of their family members who in some cases are being dragged away to gruesome torture chambers. In today’s world, do we know of any other violence on this scale and scope and for such an extended period of time? Shooting down a woman in the middle of the street for the crime of protesting against a soldier who is armed to the teeth- if this is not terrorism, what is? This barbarism, because it is being done by the armed forces of an occupying government, should not be called extremism? Or maybe only because these scenes have been seen repeatedly on television screens for sixty years, they should no longer stir our consciences. The military invasions of the Islamic world in recent years- with countless victims- are another example of the contradictory logic of the west. The assaulted countries, in addition to the human damage caused, have lost their economic and industrial infrastructure, their movement towards growth and development has been stopped or delayed and in some cases, has been thrown back decades. Despite all this, they are rudely being asked not to see themselves as oppressed. How can a country be turned into ruins, have its cities and towns covered in dust and then be told that it should please not view itself as oppressed? Instead of enticements to not understand and to not mention disasters, would not an honest apology be better? The pain that the Islamic world has suffered in these years from the hypocrisy and duplicity of the invaders is not less than the pain from the material damage. “ Dear youth! I have the hope that you- now or in the future- can change this mentality corrupted by duplicity, a mentality whose highest skill is hiding long-term goals and adorning malevolent objectives. Dear youth! I have the hope that you- now or in the future- can change this mentality corrupted by duplicity, a mentality whose highest skill is hiding long-term goals and adorning malevolent objectives. In my opinion, the first step in creating security and peace is reforming this violence-breeding mentality. Until double-standards dominate western policies, until terrorism- in the view of its powerful supporters- is divided into “good” and “bad” types, and until governmental interests are given precedence over human values and ethics, the roots of violence should not be searched for in other places. Unfortunately, these roots have taken hold in the depths of western political culture over the course of many years and they have caused a soft and silent invasion. Many countries of the world take pride in their local and national cultures, cultures which through development and regeneration have soundly nurtured human societies for centuries. The Islamic world is not an exception to this. However in the current era, the western world with the use of advanced tools is insisting on the cloning and replication of its culture on a global scale. I consider the imposition of western culture upon other peoples and the trivialization of independent cultures as a form of silent violence and extreme harmfulness. Humiliating rich cultures and insulting the most honored parts of these, is occurring while the alternative culture being offered in no way has any qualification for being a replacement. For example, the two elements of “aggression” and “moral promiscuity” which unfortunately have become the main elements of western culture, has even degraded the position and acceptability of its source region. So now the question is: are we “sinners” for not wanting an aggressive, vulgar and fatuous culture? Are we to be blamed for blocking the flood of impropriety that is directed towards our youth in the shape of various forms of quasi-art? I do not deny the importance and value of cultural interaction. Whenever these interactions are conducted in natural circumstances and with respect for the receiving culture, they result in growth, development and richness. On the contrary, inharmonious interactions have been unsuccessful and harmful impositions. We have to state with full regret that vile groups such as DAESH are the spawn of such ill-fated pairings with imported cultures. If the matter was simply theological, we would have had to witness such phenomena before the colonialist era, yet history shows the contrary. Authoritative historical records clearly show how colonialist confluence of extremist and rejected thoughts in the heart of a Bedouin tribe, planted the seed of extremism in this region. How then is it possible that such garbage as DAESH comes out of one of the most ethical and humane religious schools who as part of its inner core, includes the notion that taking the life of one human being is equivalent to killing the whole humanity? One has to ask why people who are born in Europe and who have been intellectually and mentally nurtured in that environment are attracted to such groups? Can we really believe that people with only one or two trips to war zones, suddenly become so extreme that they can riddle the bodies of their compatriots with bullets? On this matter, we certainly cannot forget about the effects of a life nurtured in a pathologic culture in a corrupt environment borne out of violence. On this matter, we need complete analyses, analyses that see the hidden and apparent corruptions. Maybe a deep hate- planted in the years of economic and industrial growth and borne out of inequality and possibly legal and structural prejudice- created ideas that every few years appear in a sickening manner. “ Any rushed and emotional reaction which would isolate, intimidate and create more anxiety for the Muslim communities living in Europe and America not only will not solve the problem but will increase the chasms and resentments. In any case, you are the ones that have to uncover the apparent layers of your own society and untie and disentangle the knots and resentments. Fissures have to be sealed, not deepened. Hasty reactions is a major mistake when fighting terrorism which only widens the chasms. Any rushed and emotional reaction which would isolate, intimidate and create more anxiety for the Muslim communities living in Europe and America- which are comprised of millions of active and responsible human beings- and which would deprive them of their basic rights more than has already happened and which would drive them away from society- not only will not solve the problem but will increase the chasms and resentments. Superficial measures and reactions, especially if they take legal forms, will do nothing but increase the current polarizations, open the way for future crises and will result in nothing else. According to reports received, some countries in Europe have issued guidelines encouraging citizens to spy on Muslims. This behavior is unjust and we all know that pursuing injustice has the characteristic of unwanted reversibility. Besides, the Muslims do not deserve such ill-treatment. For centuries, the western world has known Muslims well- the day that westerners were guests in Islamic lands and were attracted to the riches of their hosts and on another day when they were hosts and benefitted from the efforts and thoughts of Muslims- they generally experienced nothing but kindness and forbearance. Therefore I want you youth to lay the foundations for a correct and honorable interaction with the Islamic world based on correct understanding, deep insight and lessons learned from horrible experiences. In such a case and in the not too distant future, you will witness the edifice built on these firm foundations which creates a shade of confidence and trust which cools the crown of its architect, a warmth of security and peace that it bequests on them and a blaze of hope in a bright future which illuminates the canvass of the earth. Sayyid Ali Khamenei 8th of Azar, 1394 - 29th of Nov, 2015

Becoming familiar with some of the sweet concepts of the Sha’baniya Supplication / Session 3 In the name of God, the Beneficent, the Merciful. In talking about the Sh’abaniya Supplication, we are still talking about the first phrase. There is a very lofty concept in the first phrase, which should be discussed separately. This concept is “Tadarru” (beseeching). The Commander of the Faithful, Ali (‘a), explicitly calls to the God of the universe, “I am standing between Your hands. I am poor before You and beseeching You.” I am standing in front of You like one who is very small and poor in front of one who is completely rich and great, “…and beseeching You.” Beseeching is a term, which has been used seven times in the Holy Qur’an with the same meaning. Of course, it’s more than seven times. But, only in seven cases has it been used with exactly the same meaning of a person praying to God pleadingly. The fundamental meaning of beseeching is not crying. Crying is one of its results. It is the height of pleading, entreating, and being humble in front of the Almighty God. If we want to say the meaning, a person who beseeches is one who pleads a lot. A person who beseeches is one who doesn’t have any pride or assets. He’s extremely humble. It has been said in the Holy Qur’an, “Already We have seized them with punishment, but they neither humbled themselves to their Lord, nor did they beseech Him.” [Qur’an 23:76] After feeling distress and destitution, they didn’t beseech God! In this supplication, it is as if by saying, “I am poor before You and beseeching You,” the Imam is answering this verse from the Chapter “The Believers.” The Qur’an says, “We have seized them with punishment, but they neither humbled themselves to their Lord...” Imam Ali replies here, “I am poor before You.” And the Qur’an says, “…nor did they beseech Him.” Imam Ali says in this supplication, “…and beseeching You.” Beseeching has been mentioned in the Qur’an in different situations. Beseeching is a kind of pleading, which isn’t hidden anymore and is apparent. This broken heart shows itself, “Pray to your Lord beseechingly and in secret.” [Qur’an 7:55] This means to call God beseechingly, meaning openly, or hidden within yourself. There are other verses, which refer to this too. The verse of the Chapter “The Cattle” is suitable for these days. “Why did they not entreat when Our punishment overtook them! But their hearts had hardened, and Satan had made to seem decorous to them what they had been doing.” [Qur’an 6:43] Why didn’t they beseech Us when our punishment overtook them? The Almighty God tells what He expects explicitly. When a divine tribulation comes, the servants should beseech Him. God is waiting to bring His servants under His shelter. In this verse, God asks why they didn’t beseech Him. The reason they didn’t beseech Him was that their hearts had become so hardened that they didn’t even go to God in tribulations, “Satan had made to seem decorous to them what they had been doing.” In the verse before this verse, God the Almighty says that He has sent this scourge for people to beseech Him, “We have certainly sent (apostles) to nations before you, then We seized them with stress and distress so that they might entreat (Us).” [Qur’an 6:42] For us common people, this kind of beseeching God is elicited in tribulations. For those who don’t beseech God, even in tribulations, their hearts have truly become hardened as the Qur’an says. But, for people with understanding and the Friends of God, beseeching God is the result of their deep understanding, extreme interest and intense ardor for the high position of being close to God. We should resolve this riddle in our minds once and forever, that is this extent of crying needed when talking to God that the Commander of the Faithful moaned to God like this? What did he really want? What punishment did he fear?! We should accept that there is a spiritual maturity, which many don’t achieve at all. This spiritual maturity is more than fearing punishment, more than the intensity of suffering that a person will tolerate in Hell, and more than the fear of a sinful person or a criminal of retribution. Some good people feel such a severe need for being close to God that if they see they are far from this intense need, even a bit, they cry to God beseechingly. Was the Commander of the Faithful a weak person for someone to see his crying, broken heart? All his existence was solidity. If the entire universe had turned upside down, he would have stood firmly and wouldn’t have even flinched! He had nothing to be afraid of or to lose. So, why did he moan to God like this? He had reached a spiritual maturity. He felt a severe need for those high spiritual positions. When he felt a bit far from that desirable point, and that peak became more novel and substantial for him every moment, he would cry pleadingly.
