Hadith 6422

(حديث مرفوع) حَدَّثَنَا عَلِيُّ بْنُ حَفْصٍ ، أَخْبَرَنَا وَرْقَاءُ ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ ، عَنِ ابْنِ عُمَرَ , أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " نَهَى عَنِ الْقَزَعِ فِي الرَّأْسِ " .
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "He forbade qaza." Qaza means that when cutting a child's hair, some hair is cut and some is left (as is the fashion nowadays).
