(Imām Bukhārī narrates): Abū al-Nu'mān narrated to us, he said: Hammād narrated to us, from Ghailān ibn Jarīr, from Mutarrif ibn 'Abdullāh, he narrates that:
I and 'Imrān ibn Husain prayed behind 'Alī ibn Abī Tālib, may Allāh be pleased with him. Whenever he performed sajdah, he pronounced "Allāhu Akbar," and when he raised his head from sajdah, he pronounced "Allāhu Akbar," and when he stood up after two rak'ahs, he pronounced "Allāhu Akbar." When he completed the prayer, 'Imrān ibn Husain, may Allāh be pleased with him, took my hand and said: He has reminded me of the prayer of Sayyidunā Muhammad ﷺ — or he said: He has led us in the prayer of Sayyidunā Muhammad ﷺ.
حَدَّثَنَا أَبُو النُّعْمَانِ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ غَيْلاَنَ بْنِ جَرِيرٍ، عَنْ مُطَرِّفِ بْنِ عَبْدِ اللَّهِ، قَالَ صَلَّيْتُ خَلْفَ عَلِيِّ بْنِ أَبِي طَالِبٍ ـ رضى الله عنه ـ أَنَا وَعِمْرَانُ بْنُ حُصَيْنٍ،، فَكَانَ إِذَا سَجَدَ كَبَّرَ، وَإِذَا رَفَعَ رَأْسَهُ كَبَّرَ، وَإِذَا نَهَضَ مِنَ الرَّكْعَتَيْنِ كَبَّرَ، فَلَمَّا قَضَى الصَّلاَةَ أَخَذَ بِيَدِي عِمْرَانُ بْنُ حُصَيْنٍ فَقَالَ قَدْ ذَكَّرَنِي هَذَا صَلاَةَ مُحَمَّدٍ صلى الله عليه وسلم. أَوْ قَالَ لَقَدْ صَلَّى بِنَا صَلاَةَ مُحَمَّدٍ صلى الله عليه وسلم.
