Hadith 2:481
Hudhaifah said that he prayed along with the Prophet (ﷺ), and that he said when bowing, “Glory be to my mighty Lord, “ and when he prostrated himself, “Glory be to my most high Lord," when he came to a verse which spoke of mercy, he stopped and made supplication, and when he came to a verse which spoke of punishment, he stopped and sought refuge in Allah.
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، قَالَ قُلْتُ لِسُلَيْمَانَ أَدْعُو فِي الصَّلاَةِ إِذَا مَرَرْتُ بِآيَةِ تَخَوُّفٍ فَحَدَّثَنِي عَنْ سَعْدِ بْنِ عُبَيْدَةَ عَنْ مُسْتَوْرِدٍ عَنْ صِلَةَ بْنِ زُفَرَ عَنْ حُذَيْفَةَ أَنَّهُ صَلَّى مَعَ النَّبِيِّ صلى الله عليه وسلم فَكَانَ يَقُولُ فِي رُكُوعِهِ " سُبْحَانَ رَبِّيَ الْعَظِيمِ " . وَفِي سُجُودِهِ " سُبْحَانَ رَبِّيَ الأَعْلَى " . وَمَا مَرَّ بِآيَةِ رَحْمَةٍ إِلاَّ وَقَفَ عِنْدَهَا فَسَأَلَ وَلاَ بِآيَةِ عَذَابٍ إِلاَّ وَقَفَ عِنْدَهَا فَتَعَوَّذَ
