It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: A Muslim has six rights over another Muslim. The companions asked, "O Messenger of Allah (peace and blessings be upon him), what are they?" He said: When you meet him, greet him with Salam; when he invites you, accept his invitation; when he seeks your advice, give him sincere advice; when he sneezes and says Alhamdulillah, respond to him (by saying Yarhamuk Allah); when he is ill, visit him; and when he dies, accompany his funeral.
