The Prophet ﷺ recited Surat Al-Baqarah, Al 'Imran and An-Nisa' in one rak'ah, and he did not reach any verse that spoke of mercy but he asked Allah for it, nor any verse that spoke of punishment but he asked Allah for protection therefrom. (Using translation from Nasāʾī 1009)
أَنَّ النَّبِيَّ ﷺ «قَرَأَ الْبَقَرَةَ وَآلَ عِمْرَانَ وَالنِّسَاءَ فِي رَكْعَةٍ لَا يَمُرُّ بِآيَةِ رَحْمَةٍ إِلَّا سَأَلَ وَلَا بِآيَةِ عَذَابٍ إِلَّا اسْتَجَارَ»
