Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him) that he (peace be upon him) said: "When two people abuse each other, the sin is upon the one who started it, as long as the oppressed (the one who was abused first) does not exceed the limits."

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him) that he said: "When two people exchange insults, the sin is upon the one who started it, as long as the wronged one does not exceed the limits."

And the Prophet ( صلی اللہ علیہ وسلم ) said: "Do you know what «عضه» (slander) is?" The people replied: Allah and His Messenger know best. He said: "It is conveying a statement from one person to another so that discord arises among them."

And the Prophet ( صلی اللہ علیہ وسلم ) said: "Allah, the Mighty and Majestic, has revealed to me that you should adopt humility, and that none of you should wrong another."
