Sunan an-Nasa'i, Book 48, Hadith 213 (In-Book) ⓘ
It was narrated that 'Abdullah said: "May Allah curse Al-Mutanammisat and who have their teeth separated. Shall I not curse those whom the Messenger of Allah [SAW] cursed?"
أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ لَعَنَ اللَّهُ الْمُتَنَمِّصَاتِ وَالْمُتَفَلِّجَاتِ أَلاَ أَلْعَنُ مَنْ لَعَنَ رَسُولُ اللَّهِ صلى الله عليه وسلم .
