عَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ حَقُّ اَلْمُسْلِمِ عَلَى اَلْمُسْلِمِ سِتٌّ: إِذَا لَقِيتَهُ فَسَلِّمْ عَلَيْهِ, وَإِذَا دَعَاكَ فَأَجِبْهُ, وَإِذَا اِسْتَنْصَحَكَ فَانْصَحْهُ, وَإِذَا عَطَسَ فَحَمِدَ اَللَّهَ فَسَمِّتْهُ 1 وَإِذَا مَرِضَ فَعُدْهُ, وَإِذَا مَاتَ فَاتْبَعْهُ } رَوَاهُ مُسْلِمٌ 2 .
Abu Hurairah (RAA) narrated that the Messenger of Allah (ﷺ) said: “A Muslim has six duties towards other Muslims: When you meet him, you should salute him; when he invites you, accept his invitation; when he asks for your advice, give it to him; when he sneezes and praises Allah, say May Allah have mercy on you; when he is ill, visit him; and when he dies follow his funeral.” Related by Muslim.
