Sahih Bukhari Volume 7, Book 77, Hadith 5943

حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا هِشَامٌ، أَنَّهُ سَمِعَ فَاطِمَةَ بِنْتَ الْمُنْذِرِ، تَقُولُ سَمِعْتُ أَسْمَاءَ، قَالَتْ سَأَلَتِ امْرَأَةٌ النَّبِيَّ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ ابْنَتِي أَصَابَتْهَا الْحَصْبَةُ، فَامَّرَقَ شَعَرُهَا، وَإِنِّي زَوَّجْتُهَا أَفَأَصِلُ فِيهِ فَقَالَ ‏"‏ لَعَنَ اللَّهُ الْوَاصِلَةَ وَالْمَوْصُولَةَ ‏"

Narrated By Asma' : A woman asked the Prophet saying, "0 Allah's Apostle! My daughter got measles and her hair fell out. Now that I got her married, may I let her use false hair?" He said (to her), "Allah has cursed the lady who lengthens hair artificially and the one who gets her hair lengthened artificially."
