Mutarrif said:

I and ‘Imran b. Husain offered prayer behind ‘All b. AbI Talib(may Allah be pleased with him). When he prostrated, he uttered the takbir (Allah is most great) and when he bowed, he uttered the takbir and when he stood up at the end of two rak’ahs, he uttered the takbir. When we finished our prayer, ‘Imran caught hold of my hand, and said: He has led us in prayer just now like the prayer offered by Muhammed(may peace by upon him).

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادٌ، عَنْ غَيْلاَنَ بْنِ جَرِيرٍ، عَنْ مُطَرِّفٍ، قَالَ صَلَّيْتُ أَنَا وَعِمْرَانُ بْنُ حُصَيْنٍ، خَلْفَ عَلِيِّ بْنِ أَبِي طَالِبٍ - رضى الله عنه - فَكَانَ إِذَا سَجَدَ كَبَّرَ وَإِذَا رَكَعَ كَبَّرَ وَإِذَا نَهَضَ مِنَ الرَّكْعَتَيْنِ كَبَّرَ فَلَمَّا انْصَرَفْنَا أَخَذَ عِمْرَانُ بِيَدِي وَقَالَ لَقَدْ صَلَّى هَذَا قِبَلَ أَوْ قَالَ لَقَدْ صَلَّى بِنَا هَذَا قِبَلَ صَلاَةِ مُحَمَّدٍ صلى الله عليه وسلم ‏.‏
