Mutarrif said: Imran bin Husayn (may Allah be pleased with him) and I prayed behind Ali bin Abi Talib (may Allah be pleased with him). When he prostrated and when he raised his head from prostration, he said the takbir. When we had finished the prayer, Imran (may Allah be pleased with him), holding my hand, said to me: This man led us in a prayer like the prayer of the Messenger of Allah (peace and blessings be upon him).
