Al-Matalib al-'Aliyah 2732 — Prohibition of seeking out people's

It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) once delivered such a (stirring) sermon to us that his (peace and blessings be upon him) blessed voice was heard even by the young maidens who were in their homes, or (the narrator is in doubt) he said: "who were staying behind their curtains." He (peace and blessings be upon him) said: "O you group who have believed with your tongues while faith has not yet entered your hearts! Do not backbite the Muslims and do not pry into their faults and hidden matters; for whoever pursues the faults of his (Muslim) brother, Allah Almighty pursues his faults, and whoever Allah pursues in his faults, He disgraces him (even while he hides) inside his own house."
Musnad Abi Ya'la: 2732. Its chain contains Hamzah bin Habib al-Zayyat, who is an imam in the science of Qur'anic recitation, but his memory in hadith has been criticised; however, this hadith has several supporting narrations in Sunan Abi Dawud (4880), Jami' al-Tirmidhi (2032) and elsewhere, by which this narration reaches the grade of hasan li-ghayrihi (good due to supporting narrations).
