Mentioning the Prohibition of Shaving Part of a Boy's Head and Leaving Part
أَخْبَرَنَا أَحْمَدُ بْنُ عَبْدَةَ، قَالَ أَنْبَأَنَا حَمَّادٌ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنِ الْقَزَعِ .
It was narrated from Ibn 'Umar that: The Prophet (ﷺ) [SAW] forbade Al-Qaza' (shaving part of the head and leaving part).
