Musannaf Ibn Abi Shaybah

Hazrat Yazid bin Hayan (may Allah have mercy on him) narrates that Anbas bin Uqbah al-Taimi (may Allah have mercy on him) (i.e., from the tribe of Taim al-Rabab), when he would prostrate, birds would come and sit on his back and then fly away. The birds considered him to be nothing more than a piece of wall.
