Sama says that he came to Imam Ja’far as-Sadiq who began the conversation, “O Sama!” what is it that I have heard between you and your camel driver? See that you do not become an abuser and curser.”
Sama replied, “Yes! What you have heard is correct. He had been unjust on me.”
Imam (a.s.) said,
“If he has oppressed you, you have also become his equal and you oppressed more. Indeed this action is not from my behaviour and neither do I advise my Shias to do like that. Ask your Lord for forgiveness and do not repeat this act.”( Al – Kafi )
