ahmad-zuhd:629ʿAbdullāh > Bī > Sayyār > Jaʿfar > Hishām > al-Ḥasan > ʿUmar

[Machine] That Umar ibn al-Khattab used to come across the verse in his recitation and it would choke him, so he would stay at home for days and they would think he was sick.  

الزهد لأحمد:٦٢٩حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا أبِي حَدَّثَنَا سَيَّارٌ حَدَّثَنَا جَعْفَرٌ حَدَّثَنَا هِشَامٌ عَنِ الْحَسَنِ

أَنَّ عُمَرَ بْنَ الْخَطَّابِ ؓ كَانَ يَمُرُّ بِالْآيَةِ فِي وِرْدِهِ فَتَخْنُقُهُ فَيَبْقَى فِي الْبَيْتِ أَيَّامًا يُعَادُ يَحْسَبُونَهُ مَرِيضًا
