It is narrated from Hazrat Abu Barzah Aslami (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) once said: O people who have believed with their tongues but faith has not entered their hearts! Do not backbite the Muslims and do not seek out their faults, for whoever seeks out their faults, Allah will seek out his faults, and whoever Allah seeks out his faults, He will disgrace him in his own home.
