Musannaf Ibn Abi Shayba 33:451

Yahya ibn Adam narrated to us, from Ammar ibn Zurayq, from Abu Ishaq, from Aws ibn Dam'aj, who said: We said to Salman, "O Abu Abd Allah, will you not narrate to us?" He said, "The remembrance of Allah is greater, and feeding food, and spreading peace, and praying while the people are asleep."
