عَنْ حُذَيْفَةَ بْنِ الْيَمَانِ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ إِذَا مَرَّ بِآيَةِ رَحْمَةٍ سَأَلَ وَإِذَا مَرَّ بِآيَةٍ فِيهَا عَذَابٌ تَعَوَّذَ وَإِذَا مَرَّ بِآيَةٍ فِيهَا تَنْزِيهٌ لِلَّهِ عَزَّ وَجَلَّ سَبَّحَ
It is narrated from Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with them both) that when the Noble Prophet (peace and blessings be upon him) would recite a verse mentioning mercy, he would ask Allah for it; when he would pass by a verse mentioning punishment, he would seek refuge; and when he would pass by a verse in which Allah’s sanctity was declared, he would glorify Him.
