Abu Hurairah (RAA) narrated that the Messenger of Allah (ﷺ) said:

“A sign of man's good observance of Islam (his piety) is to keep away from that which does not concern him.” Related by At-Tirmidhi who graded it as Hadith Hasan.

وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ مِنْ حُسْنِ إِسْلَامِ اَلْمَرْءِ, تَرْكُهُ مَا لَا يَعْنِيهِ } رَوَاهُ اَلتِّرْمِذِيُّ, وَقَالَ حَسَنٌ.‏ [1]‏ .‏
