It was narrated from ʼUmar that:

The Prophet (ﷺ) said: `The deceased is tormented in his grave because of the wailing for him.`

حَدَّثَنَا يَحْيَى، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا قَتَادَةُ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْمَيِّتُ يُعَذَّبُ فِي قَبْرِهِ بِالنِّيَاحَةِ عَلَيْهِ‏.‏
