It is narrated from Sayyiduna Miqdam (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever dies leaving a debt behind, he is under the responsibility of Allah and His Messenger, and whoever dies leaving wealth, it will belong to his heirs. And the maternal uncle is the heir of the one who has no heir, and I am the heir of the one who has no heir; I am his heir and I will pay his blood money on his behalf."
