Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Salamah that the companions of the Noble Prophet Muhammad (peace and blessings be upon him) were neither miserly nor weak in performing acts of worship. In their gatherings, they would recite poetry and recall matters from the days of ignorance. But when any of them was intended for something concerning their religion, his eyelids would turn as if he were insane.
