We surely know that our Imams A.S. are infallible. However, They have been oppressed during their life. They A.S. have to tolerate oppression out of necessity. They have also advised their followers to remain patient against oppressors in many narrations. If tolerating oppression is a sin according to your speech, have our divinely ordained and infallible Imams A.S. and their true followers been sinners? Only because they have been tolerating oppression out of necessity. Thank You in advance for prompt reply.
