It is narrated from Sayyiduna Abu Habib al-Anbari (may Allah be pleased with him) that he came to the Messenger of Allah (peace and blessings be upon him) seeking his help against a debtor of his. He (peace and blessings be upon him) said to him: "Stay close to him." Later, he (peace and blessings be upon him) met him and said: "O brother of Banu al-Anbar, what has become of your captive?"
