Musannaf Ibn Abi Shayba 13:967

Abu Bakr narrated to us, he said: Zayd ibn al-Hubab and Ubayd Allah narrated to us, from Abu Hilal, from Ghalib al-Qattan, from Abu al-Muhazzam, that a man came to Abu Hurayrah regarding a debtor of his and said: "Imprison him." Abu Hurayrah said: "Do you know of any liquid assets he has so that I may seize them for you?" He said: "No." He said: "Do you know of any real estate he has so that I may break it [sell/liquidate it]?" He said: "No." He said: "Then what do you want?" He said: "Imprison him." He said: "No, but I will leave him to seek [provision] for you, for himself, and for his family."
