Muwatta Imam Malik Book of Good Character, Hadith 3

Yahya related to me from Malik from Ibn Shihab from Ali ibn Husayn ibn Ali ibn Abi Talib that the Messenger of Allah ﷺ said, "Part of the excellence of a man's Islam is that he leaves what does not concern him."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَلِيِّ بْنِ حُسَيْنِ بْنِ عَلِيِّ بْنِ أَبِي طَالِبٍ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " مِنْ حُسْنِ إِسْلاَمِ الْمَرْءِ تَرْكُهُ مَا لاَ يَعْنِيهِ " .
