Mishkat al-Masabih
Nafi‘ quoted Ibn ‘Umar as saying he had heard the Prophet (ﷺ) forbidding qaza'. Nafi' was asked what qaza’ was and replied that it was having part of a boy’s head shaved arid leaving part unshaven. (Bukhari and Muslim.) Some made the explanation a part of the tradition.
وَعَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَنْهَى عَنِ الْقَزَعِ. قِيلَ لِنَافِعٍ: مَا الْقَزَعُ؟ قَالَ: يُحْلَقُ بعضُ رَأس الصبيِّ وَيتْرك البعضُ وَألْحق بَعضهم التَّفْسِير بِالْحَدِيثِ
