The Messenger of Allah ﷺ said, "The Muslim has six rights upon his fellow Muslim."Someone asked, "What are they, Messenger of Allah?"He replied, "When you meet him, greet him with salaam. When he invites you, accept his invitation. When he seeks your counsel, give him sincere advice. When he sneezes and praises Allah, respond with a blessing. When he falls ill, visit him. And when he dies, follow his funeral procession."
حدثنا يحيى بن أيوب وقتيبة وابن حجر قالوا حدثنا إسمعيل وهو ابن جعفر عن العلاء عن أبيه
أن رسول الله ﷺ قال حق المسلم على المسلم ست قيل ما هن يا رسول الله قال إذا لقيته فسلم عليه وإذا دعاك فأجبه وإذا استنصحك فانصح له وإذا عطس فحمد الله فسمته وإذا مرض فعده وإذا مات فاتبعه
