Sahih al-Bukhari 785

It is related that Mutarrif said, "'Imran ibn Husayn and I prayed behind 'Ali ibn Abi Talib. When he went into sajda he said the takbir and when he raised his head, he said the takbir. When he got up after two rak'ats, he said the takbir. When he finished the prayer, 'Imran ibn Husayn took hold of my hand and said, 'This man reminded me of the prayer of Muhammad, may Allah bless him and grant him peace,' or he said, 'He prayed the prayer of Muhammad, may Allah bless him and grant him peace, with us.'" LXI: The sunna of how to sit during the tashahhud Umm ad-Darda' used to sit in her prayer like a man sits and she was a faqiha.
