The Book of Adornment
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 .
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?
