عن ابن عمر رضي الله عنهما، قال: نهى رسول الله ﷺ عن القَزَع.
Ibn ‘Umar (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) forbade Qaza‘.
The Prophet (may Allah's peace and blessings be upon him) forbade shaving part of a boy's head and leaving other parts unshaven. This forbiddance is general, and it applies to everyone.
