`Ali b. Ahmad b. `Abdullah b. Ahmad b. Abi `Abdillah al-Barqi narrated to us. He said: My father narrated to us from his grandfather Ahmad b. Abi `Abdillah from al-Hasan b. `Ali b. Faddal from `Abdullah b. Bukayr from Zurara b. A`yan. He said: I heard Aba Ja`far Muhammad b. `Ali al-Baqir say:

A man entered a mosque wherein which was the Messenger of Allah (s) and lightened (hastened) his prostration in a way that was unbefitting for a prostration. So, the Messenger of Allah (s) said: He pecked like the pecking of a crow. If he dies upon this, then he dies upon a religion other than the religion of Muhammad.
