Sahih Muslim

Book 15: The Book of Pilgrimage

Chapter 55

Shaving the head is preferrable to cutting the hair, although cutting the hair is permissible

باب تَفْضِيلِ الْحَلْقِ عَلَى التَّقْصِيرِ وَجَوَازِ التَّقْصِيرِ ‏‏

Sahih Muslim 1301d
وَحَدَّثَنَاهُ ابْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا عُبَيْدُ اللَّهِ، بِهَذَا الإِسْنَادِ وَقَالَ فِي الْحَدِيثِ فَلَمَّا كَانَتِ الرَّابِعَةُ قَالَ ‏ ‏ ‏.‏
"‏ وَالْمُقَصِّرِينَ ‏"
Ubaidullah reported this hadith with the same chain of transmitters and (it is said) that it was on the fourth turn that he (the Holy Prophet) said:

(May Allah have mercy upon) those who got their hair clipped."
