Sahih Muslim , Book 4, Hadith 769 (USC-MSA) ⓘ
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 used to do like that.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ كَانَ يُكَبِّرُ كُلَّمَا خَفَضَ وَرَفَعَ وَيُحَدِّثُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَفْعَلُ ذَلِكَ .
