It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I am closer to the believers than their own selves. Whoever leaves wealth, his wealth is for his agnatic heirs ('asabah); and whoever leaves debt or children and the like, I am his guardian."
