عَنْ سَعِيدٍ الْمَقْبُرِيِّ عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: أَنَا أَشْبَهُكُمْ صَلَاةً بِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا قَالَ ((سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ)) قَالَ ((اللَّهُمَّ رَبَّنَا وَلَكَ الْحَمْدُ)) قَالَ وَكَانَ يُكَبِّرُ إِذَا رَكَعَ وَإِذَا قَامَ مِنَ السُّجُودِ، وَإِذَا رَفَعَ رَأْسَهُ مِنَ السَّجْدَتَيْنِ
Sayyiduna Abu Hurairah (may Allah be pleased with him) says: Among all of you, I resemble the Messenger of Allah (peace and blessings be upon him) the most in prayer. When the Prophet (peace and blessings be upon him) would say "Sami' Allahu liman hamidah," he would then say "Allahumma Rabbana wa lakal hamd." And when he (peace and blessings be upon him) would bow (in ruku'), stand up from prostration, and raise his head from the two prostrations, he would say the takbir.
