(32) باب قَوْلِ النَّبِيِّ صلى الله عليه وسلم: «يُعَذَّبُ الْمَيِّتُ بِبَعْضِ بُكَاءِ أَهْلِهِ عَلَيْهِ» إِذَا كَانَ النَّوْحُ مِنْ سُنَّتِهِ
Narrated Abu Burda:
That his father said, "When `Umar was stabbed, Suhaib started crying: O my brother! `Umar said, 'Don't you know that the Prophet (ﷺ) said: The deceased is tortured for the weeping of the living'?"
