The statement of the Prophet (ﷺ) ﷺ : "The deceased is punished because of the weeping (with wailing) of some of his relatives, if wailing was the custom of that dead person."
حَدَّثَنَا إِسْمَاعِيلُ بْنُ خَلِيلٍ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، حَدَّثَنَا أَبُو إِسْحَاقَ ـ وَهْوَ الشَّيْبَانِيُّ ـ عَنْ أَبِي بُرْدَةَ، عَنْ أَبِيهِ، قَالَ لَمَّا أُصِيبَ عُمَرُ ـ رضى الله عنه ـ جَعَلَ صُهَيْبٌ يَقُولُ وَاأَخَاهُ. فَقَالَ عُمَرُ أَمَا عَلِمْتَ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " إِنَّ الْمَيِّتَ لَيُعَذَّبُ بِبُكَاءِ الْحَىِّ ".
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'?"
