What (sort of) wailing over a deceased is disliked
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سَعِيدُ بْنُ عُبَيْدٍ، عَنْ عَلِيِّ بْنِ رَبِيعَةَ، عَنِ الْمُغِيرَةِ ـ رضى الله عنه ـ قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " إِنَّ كَذِبًا عَلَىَّ لَيْسَ كَكَذِبٍ عَلَى أَحَدٍ، مَنْ كَذَبَ عَلَىَّ مُتَعَمِّدًا فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ ". سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " مَنْ نِيحَ عَلَيْهِ يُعَذَّبُ بِمَا نِيحَ عَلَيْهِ ".
Narrated Al-Mughira: I heard the Prophet (ﷺ) saying, "Ascribing false things to me is not like ascribing false things to anyone else. Whosoever tells a lie against me intentionally then surely let him occupy his seat in Hell-Fire." I heard the Prophet (ﷺ) saying, "The deceased who is wailed over is tortured for that wailing."
