Sahih Muslim 2122 a
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.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ بِنْتِ،
 الْمُنْذِرِ عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ، قَالَتْ جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَتْ
 يَا رَسُولَ اللَّهِ إِنَّ لِي ابْنَةً عُرَيِّسًا أَصَابَتْهَا حَصْبَةٌ فَتَمَرَّقَ شَعْرُهَا أَفَأَصِلُهُ فَقَالَ ‏
"‏ لَعَنَ
 اللَّهُ الْوَاصِلَةَ وَالْمُسْتَوْصِلَةَ ‏"‏ ‏.‏
