This tradition has also been transmitted by Abdullah (bin Masud) through a different chain of narrators. This version goes; when one of you forgets (in his prayer), he should perform two prostrations. Then he turned away, and performed two prostrations (due to forgetfulness). Abu Dawud said: The narrator Husain also reported it like al-Amash.
