It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both), he said: We were with the Messenger of Allah (peace and blessings of Allah be upon him) when a foul wind blew, so the Prophet (peace and blessings of Allah be upon him) asked: "Do you know what this is? This is the foul wind of those people who used to backbite the believers."

It is narrated from Sayyiduna Abu Sufyan bin Jabir (may Allah be pleased with him), he says that during the blessed era of the Messenger of Allah (peace and blessings of Allah be upon him), a foul-smelling wind blew, so the Messenger of Allah (peace and blessings of Allah be upon him) said: "Some hypocrites have backbitten some Muslims, and because of this, this wind has been sent."

It is narrated from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him), he says: Whoever, in whose presence a believer is backbitten and he helps him, Allah Almighty will reward him in this world and the Hereafter. And whoever, in whose presence a Muslim is backbitten and he does not help him, that is, does not defend him, Allah Almighty will give him an evil recompense in this world and the Hereafter. And no one has put a worse morsel in his mouth than backbiting a believer. If he says something about him which he knows, then he has backbitten him, and if he says something about him which he does not know, then he has slandered him.
