عن ابن عمر رضي الله عنهما قال‏:‏ نهى رسول الله صلى الله عليه وسلم عن القزع‏.‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

Ibn 'Umar (May Allah be pleased with them) said

The Messenger of Allah (ﷺ) saw a boy, some portion of whose head was shaved and some of it was left out. He prohibited them from that and said, "Shave the whole of it or leave the whole of it."[Muslim].
