It is narrated from Sayyiduna Ali (may Allah be pleased with him) that when the following verse was revealed: «﴿وَأَنْذِرْ عَشِيرَتَكَ الْأَقْرَبِينَ﴾ [الشعراء: 214] » , the Prophet (peace and blessings be upon him) gathered his family members, thirty people assembled and all of them ate and drank. The Prophet (peace and blessings be upon him) said to them: "Who will guarantee the fulfillment of my debts and promises so that he will be with me in Paradise, and will be my deputy among my family?" Later, someone said to the Prophet (peace and blessings be upon him): O Messenger of Allah! You were like an ocean, who could stand in your place? In any case, the Prophet (peace and blessings be upon him) said the same to another, and finally, when he presented this invitation before his household, Sayyiduna Ali (may Allah be pleased with him) said: O Messenger of Allah! I will do this.
