It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "I have more right than anyone to the well-being of every believer in this world and the Hereafter. Recite, if you wish: 'The Prophet is closer to the believers than their own selves' [Surah al-Ahzab: 6]. Whoever leaves wealth, it is for his heirs, and whoever leaves a burden (of debt) or the like, I will settle it on his behalf."
