The Messenger of Allah ﷺ prayed, bowing four times, and he recited loudly, and every time he raised his head he said: "Sami Allahu liman hamidah. Rabbana wa lakal-hamd (Allah hears those who praise Him, Our Lord to You be praise.)."
عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ صَلَّى أَرْبَعَ رَكَعَاتٍ فِي أَرْبَعِ سَجَدَاتٍ وَجَهَرَ فِيهَا بِالْقِرَاءَةِ كُلَّمَا رَفَعَ رَأْسَهُ قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ رَبَّنَا وَلَكَ الْحَمْدُ

عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ صَلَّى أَرْبَعَ رَكَعَاتٍ فِي أَرْبَعِ سَجَدَاتٍ وَجَهَرَ فِيهَا بِالْقِرَاءَةِ كُلَّمَا رَفَعَ رَأْسَهُ قَالَ «سَمِعَ اللهُ لِمَنْ حَمِدَهُ رَبِّنَا وَلَكَ الْحَمْدُ»
