باب الْوَصْلِ فِي الشَّعَرِ
Sahih al-Bukhari 5935

Narrated Asma:

(the daughter of Abu' Bakr) A woman came to Allah's Messenger (ﷺ) and said, "I married my daughter to someone, but she became sick and all her hair fell out, and (because of that) her husband does not like her. May I let her use false hair?" On that the Prophet (ﷺ) cursed such a lady as artificially lengthening (her or someone else's) hair or got her hair lengthened artificially.

حَدَّثَنِي أَحْمَدُ بْنُ الْمِقْدَامِ، حَدَّثَنَا فُضَيْلُ بْنُ سُلَيْمَانَ، حَدَّثَنَا مَنْصُورُ بْنُ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَتْنِي أُمِّي، عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ ـ رضى الله عنهما ـ أَنَّ امْرَأَةً، جَاءَتْ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَتْ إِنِّي أَنْكَحْتُ ابْنَتِي، ثُمَّ أَصَابَهَا شَكْوَى فَتَمَرَّقَ رَأْسُهَا، وَزَوْجُهَا يَسْتَحِثُّنِي بِهَا أَفَأَصِلُ رَأْسَهَا فَسَبَّ رَسُولُ اللَّهِ صلى الله عليه وسلم الْوَاصِلَةَ وَالْمُسْتَوْصِلَةَ‏.‏
