It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: When this verse {وَأَنْذِرْ عَشِیرَتَکَ الْأَقْرَبِینَ} … "And warn your nearest relatives" was revealed, the Noble Prophet (peace and blessings be upon him) gathered the people of his family, thirty people gathered, they ate and drank, after that the Prophet (peace and blessings be upon him) said to them: Who among you will guarantee the repayment of my debts and the fulfillment of my promises, as a result of which he will be with me in Paradise and will be my successor among my family? One man replied: O Messenger of Allah! You are like an ocean, who can fulfill these responsibilities? Then the Prophet (peace and blessings be upon him) said this to someone else as well. Then when the Prophet (peace and blessings be upon him) presented this matter to his household, Sayyiduna Ali (may Allah be pleased with him) said: Yes, I guarantee it.
