Muhammad bin Yusuf narrates: I heard my father narrate: Once, Sayyiduna Muawiyah (may Allah be pleased with him) led the people in prayer. After performing two rak‘ahs, he stood up again, although he was supposed to sit. The people said "Subhan Allah" at this, but he did not sit down, until when he sat for the final tashahhud to say the salam, he performed two prostrations of forgetfulness (sajda sahw). He said: I saw the Prophet Muhammad (peace and blessings be upon him) perform the prayer in this manner. The words of the narrator named Nishapuri are: I saw the Prophet Muhammad (peace and blessings be upon him) do this.
