Musannaf Ibn Abi Shayba 17:763

Yahya ibn Adam narrated to us, from Hammad ibn Zayd, from Abd al-Rahman ibn Abi Bakrah, from al-Aswad ibn Sari’, who said: I said, "O Messenger of Allah, I have composed a praise for Allah, and I have composed another for you." He said, "Bring it forth, and begin with your praise of Allah."
