6 Obligations Upon a Muslim
The Prophet (Peace Be upon Him) said:
“The rights of the Muslim upon the Muslim are six”, “When you meet him, give him the greeting of peace, When he invites you, respond to his invitation, When he seeks your advice, advise him, When he sneezes and praises Allah, supplicate for mercy upon him, When he becomes ill, visit him, and When he dies follow him (i.e. his funeral)” [Muslim]
