Musnad Abu Ya'la al-Mawsili 243:52

Abu Bakr narrated to us, Mu'tamir ibn Sulayman narrated to us, from 'Abbad ibn 'Abbad, from Abu Mijlaz, from Abu Musa, who said: We brought the Messenger of Allah (may Allah bless him and grant him peace) water for ablution, and he performed ablution. He said: "O Allah, forgive my sin, expand my home for me, and bless me in my provision."
