It was narrated that Asma' said:
"A woman came to the Prophet and said:, My daughter is going to get married, and she had the measles and her hair has fallen out. Can I put extensions in her hair?, The Messenger of Allah said: ‘Allah has cursed the one who does hair extensions and the one who has that done.'"

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ، عَنْ أَسْمَاءَ، قَالَتْ جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ ﷺ فَقَالَتْ إِنَّ ابْنَتِي عُرَيِّسٌ وَقَدْ أَصَابَتْهَا الْحَصْبَةُ فَتَمَرَّقَ شَعْرُهَا . فَأَصِلُ لَهَا فِيهِ فَقَالَ رَسُولُ اللَّهِ ﷺ " لَعَنَ اللَّهُ الْوَاصِلَةَ وَالْمُسْتَوْصِلَةَ " .
