The Forty Hadith of Imam Nawawi #12
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صلى الله عليه و سلم "مِنْ حُسْنِ إسْلَامِ الْمَرْءِ تَرْكُهُ مَا لَا يَعْنِيهِ". حَدِيثٌ حَسَنٌ، رَوَاهُ التِّرْمِذِيُّ .
On the authority of Abu Hurayrah (may Allah be pleased with him) who said:
The Messenger of Allah (peace and blessings of Allah be upon him) said, “Part of the perfection of one’s Islam is his leaving that which does not concern him.”
A hasan (good) hadeeth which was related by at-Tirmidhi and others in this fashion.
