I prayed along with the Messenger of Allah ﷺ and he used to say in his rukūʿ: ‘I glorify the perfection of Allah, the Supreme’ and his sajdah: ‘I glorify the perfection of Allah, the Most High’. He never came to an āyah of mercy except that he paused at it and asked ˹for Allah’s Mercy˺, nor he came to an āyah of punishment except that he sought the refuge ˹in Allah˺ from it.
صَلَّيْتُ مَعَ رَسُولِ اللهِ ﷺ فَكَانَ يَقُولُ فِي رُكُوعِهِ «سُبْحَانَ رَبِّيَ الْعَظِيمِ» وَفِي سُجُودِهِ «سُبْحَانَ رَبِّيَ الْأَعْلَى» قَالَ وَمَا مَرَّ بِآيَةِ رَحْمَةٍ إِلَّا وَقَفَ عِنْدَهَا فَسَأَلَ وَلَا آيَةِ عَذَابٍ إِلَّا تَعَوَّذَ مِنْهَا
