Musannaf Ibn Abi Shayba 21:271

Mu'tamir ibn Sulayman narrated to us, from 'Abbad ibn 'Abbad, from Abu Mijlaz, from Abu Musa, who said: I brought the Prophet, may Allah bless him and grant him peace, water for ablution. He performed ablution and prayed, then said: "O Allah, forgive my sin, expand my home for me, and bless me in my provision."
