حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا قَالَ " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ ". قَالَ " اللَّهُمَّ رَبَّنَا وَلَكَ الْحَمْدُ ". وَكَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ يُكَبِّرُ، وَإِذَا قَامَ مِنَ السَّجْدَتَيْنِ قَالَ " اللَّهُ أَكْبَرُ ".

Narrated Abu Huraira:When the Prophet (ﷺ) said, "Sami`a l-lahu liman hamidah," (Allah heard those who sent praises to Him), he would say, "Rabbana wa laka l-hamd." On bowing and raising his head from it the Prophet (ﷺ) used to say Takbir. He also used to say Takbir on rising after the two prostrations. (See Hadith No)
