Sahih
حَدَّثَنَا إِسْحَاقُ الْوَاسِطِيُّ، قَالَ حَدَّثَنَا خَالِدٌ، عَنِ الْجُرَيْرِيِّ، عَنْ أَبِي الْعَلاَءِ، عَنْ مُطَرِّفٍ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، قَالَ صَلَّى مَعَ عَلِيٍّ ـ رضى الله عنه ـ بِالْبَصْرَةِ فَقَالَ ذَكَّرَنَا هَذَا الرَّجُلُ صَلاَةً كُنَّا نُصَلِّيهَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم. فَذَكَرَ أَنَّهُ كَانَ يُكَبِّرُ كُلَّمَا رَفَعَ وَكُلَّمَا وَضَعَ.
Narrated `Imran bin Husain:
I offered the prayer with `Ali in Basra and he made us remember the prayer which we used to pray with Allah's Messenger (ﷺ). `Ali said Takbir on each rising and bowing.
