(33) بَاب تَحْرِيمِ فِعْلِ الْوَاصِلَةِ وَالْمُسْتَوْصِلَةِ وَالْوَاشِمَةِ وَالْمُسْتَوْشِمَةِ وَالنَّامِصَةِ وَالْمُتَنَمِّصَةِ وَالْمُتَفَلِّجَاتِ وَالْمُغَيِّرَاتِ خَلْقِ اللَّهِ
Asma', daughter of Abu Bakr, reported that a woman came to Allah's Apostle (ﷺ) and said:
I have a daughter who has been newly wedded. She had an attack of smallpox and thus her hair had fallen; should I add false hair to her head? Thereupon Allah's Messenger (ﷺ) said: Allah has cursed the woman who adds some false hair and the woman who asks for it.
