Musannaf Ibn Abi Shaybah 38253 — Sayings of Ikrimah

It is narrated from Thabit that Abu Thamir was a devoted worshipper. One day he slept before praying the Isha prayer. Two angels, or two men, came to him in his dream, and one of them sat by his head and the other by his feet. Then the one at his head said to the one at his feet: Praying before sleeping pleases the Most Merciful and angers Satan. And the one at his feet said to the one at his head: Sleeping before the prayer pleases Satan and angers the Most Merciful.
