Imam Khamenei’s Fatwa Against Insulting Sahaba فتوة السيد علي الخامنئي

We don’t insult companions, HOWEVER a respectful, intellectual, scientific research about their history is what the Shia of AhlulBayt(A) do.

So if you see any propaganda of crazy sheikhs swearing or using abusive language regarding the Prophet(S)’s companions then KNOW that he is NOT amongst the mainstream of Shia Islam.
