When 'Umar was wounded he fainted, and there was a loud lamentation over him. When he regained consciousness he said: Didn't you know that the Messenger of Allah ﷺ said:" The dead is punished because of the weeping of the living"?
طُعِنَ عُمَرُ أُغْمِيَ عَلَيْهِ فَصِيحَ عَلَيْهِ فَلَمَّا أَفَاقَ قَالَ أَمَا عَلِمْتُمْ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ الْمَيِّتَ لَيُعَذَّبُ بِبُكَاءِ الْحَىِّ
That his father said, "When ʿUmar was stabbed, Suhaib started crying: O my brother! ʿUmar said, 'Don't you know that the Prophet ﷺ said: The deceased is tortured for the weeping of the living'?"
لَمَّا أُصِيبَ عُمَرُ ؓ جَعَلَ صُهَيْبٌ يَقُولُ وَاأَخَاهُ فَقَالَ عُمَرُ أَمَا عَلِمْتَ أَنَّ النَّبِيَّ ﷺ قَالَ إِنَّ الْمَيِّتَ لَيُعَذَّبُ بِبُكَاءِ الْحَىِّ
O brother! Upon this 'Umar said: Suhaib, did you not know that the Messenger of Allah ﷺ said:" The dead is punished because of the lamentation of the living"?
لَمَّا أُصِيبَ عُمَرُ جَعَلَ صُهَيْبٌ يَقُولُ وَاأَخَاهْ فَقَالَ لَهُ عُمَرُ يَا صُهَيْبُ أَمَا عَلِمْتَ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ الْمَيِّتَ لَيُعَذَّبُ بِبُكَاءِ الْحَىِّ
