`Imran and I prayed behind `Ali bin Abi Talib and he said Takbir on prostrating, on rising and on getting up after the two rak`at (i.e. after the second rak`a). When the prayer was finished, `Imran took me by the hand and said, "He (`Ali) has prayed the prayer of Muhammad" (or said, "He made us remember the prayer of Muhammad).
