Musannaf Ibn Abi Shayba 13:1425

Abu Bakr narrated to us, he said: Abbad bin al-Awwam narrated to us, from Husayn, from Muhammad bin Ka'b, who said: A woman came to him and asked him, and she said: "Indeed, my sons and their brothers from their father are orphans under my care. I had wealth that I used to spend on them until it was gone, and they have wealth. So what do you see?" He said: "Place your hand with their hands, and eat in a recognized manner (ma'ruf)."
