When the Prophet ﷺ said: "Sami Allahu liman hamidah (Allah hears the one who praises Him),' he said: "Allahumma Rabbana wa lakal-hamd, mil'as-samawati wa mil'al-ardi wa mil'ama shi'ta min shai'in ba'd ( O Allah, our Lord, to You be the Praise, filling the heavens, filling the Earth, and filling whatever else You will.)"  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ قَالَ اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَمِلْءَ الأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَىْءٍ بَعْدُ  

When the Prophet ﷺ wanted to prostrate after bowing, he would say: "Allahumma, Rabbana wa lakal-hamd, mil'as-samawati wa mil'al-ardi wa mil'ama shi'ta min shai'in ba'd ( O Allah, our Lord, to You be the Praise, filling the heavens, filling the Earth, and filling whatever else You will.)"  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا أَرَادَ السُّجُودَ بَعْدَ الرَّكْعَةِ يَقُولُ اللَّهُمَّ رَبَّنَا وَلَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَمِلْءَ الأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَىْءٍ بَعْدُ  

The Messenger of Allah ﷺ used to say: "Sami Allahu liman hamidah, Rabbana wa lakal-hamd, mil'as-samawati wa mil'al-ardi wa mil'ama shi'ta min shai'in ba'd. Athlath-thana'i wal-majdi khairu ma qalal-'abdu wa kulluna laka 'abdun la mani'a lima a'taita wa la yanfa'u dhal-jaddi minkal-jadd (Allah hears the one who praises Him; Our Lord, to You be the Praise, filling the heavens, filling the Earth, and filling whatever else You will, Lord of Glory and Majesty, the truest thing a slave had said, and we are all slaves to You. None can withhold what You grant, nor can the possession of an owner benefit him before You.)"  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقُولُ حِينَ يَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَمِلْءَ الأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَىْءٍ بَعْدُ أَهْلَ الثَّنَاءِ وَالْمَجْدِ خَيْرُ مَا قَالَ الْعَبْدُ وَكُلُّنَا لَكَ عَبْدٌ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ  

He prayed with the Messenger of Allah ﷺ one night and he heard him say when he said the takbir: "Allahu Akbara dhal-jabaruti wal-malakuti wal-kibriya'i wal-'azamah (Allah is Most Great, the One Who has all power, sovereignty, magnificence and might.)" When bowing he would say: "Subhana Rabbial-'Azim (Glory be to my Lord Almighty)." When he raised his head from bowing he would say: "Lirabbil-hamd, Lirabbil-hamd (To my Lord be praise, to my Lord be praise)." And when he prostrated (he said): "Subhana Rabbial-A'la (Glory be to my Lord Most High)." And between the two prostrations (he said): "Rabbighfirli, Rabbighfirli (Lord forgive me, Lord forgive me)." His standing, his bowing, when he raised his head from bowing, his prostration and the time between the two prostrations, were almost the same.  

أَنَّهُ صَلَّى مَعَ رَسُولِ اللَّهِ ﷺ ذَاتَ لَيْلَةٍ فَسَمِعَهُ حِينَ كَبَّرَ قَالَ اللَّهُ أَكْبَرُ ذَا الْجَبَرُوتِ وَالْمَلَكُوتِ وَالْكِبْرِيَاءِ وَالْعَظَمَةِ وَكَانَ يَقُولُ فِي رُكُوعِهِ سُبْحَانَ رَبِّيَ الْعَظِيمِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ قَالَ لِرَبِّي الْحَمْدُ لِرَبِّي الْحَمْدُ وَفِي سُجُودِهِ سُبْحَانَ رَبِّيَ الأَعْلَى وَبَيْنَ السَّجْدَتَيْنِ رَبِّ اغْفِرْ لِي رَبِّ اغْفِرْ لِي وَكَانَ قِيَامُهُ وَرُكُوعُهُ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَمَا بَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ
