Arabic hadith text
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ كَانَيُكَبِّرُ كُلَّمَا خَفَضَ وَرَفَعَ وَيُحَدِّثُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَفْعَلُ ذَلِكَ .
Translation
Suhail reported on the authority of his father that Abu Huraira used to recite takbir on all occasions of rising and bending (in prayer) and narrated that the Messenger of Allah (ﷺ) used to do like that.
