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 dies and leaves wealth, it will be distributed among his 'asabah (i.e. his relatives), and whoever leaves a debt or helpless dependents (daya'), I am responsible for him."
