Sahih Bukhari 5920

حَدَّثَنِي مُحَمَّدٌ ، قَالَ : أَخْبَرَنِي مَخْلَدٌ ، قَالَ : أَخْبَرَنِي ابْنُ جُرَيْجٍ ، قَالَ : أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ حَفْصٍ ، أَنَّ عُمَرَ بْنَ نَافِعٍ ، أَخْبَرَهُ عَنْ نَافِعٍ مَوْلَى عَبْدِ اللَّهِ ، أَنَّهُ سَمِعَ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا ، يَقُولُ : سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : يَنْهَى عَنِ الْقَزَعِ قَالَ عُبَيْدُ اللَّهِ : قُلْتُ : وَمَا الْقَزَعُ ؟ فَأَشَارَ لَنَا عُبَيْدُ اللَّهِ قَالَ : إِذَا حَلَقَ الصَّبِيَّ وَتَرَكَ هَا هُنَا شَعَرَةً وَهَهُنَا وَهَهُنَا ، فَأَشَارَ لَنَا عُبَيْدُ اللَّهِ إِلَى نَاصِيَتِهِ وَجَانِبَيْ رَأْسِهِ قِيلَ لِعُبَيْدِ اللَّهِ : فَالْجَارِيَةُ وَالْغُلَامُ ، قَالَ : لَا أَدْرِي ، هَكَذَا قَالَ : الصَّبِيُّ ، قَالَ عُبَيْدُ اللَّهِ : وَعَاوَدْتُهُ ، فَقَالَ : أَمَّا الْقُصَّةُ وَالْقَفَا لِلْغُلَامِ فَلَا بَأْسَ بِهِمَا ، وَلَكِنَّ الْقَزَعَ أَنْ يُتْرَكَ بِنَاصِيَتِهِ شَعَرٌ وَلَيْسَ فِي رَأْسِهِ غَيْرُهُ ، وَكَذَلِكَ شَقُّ رَأْسِهِ هَذَا وَهَذَا .

Narrated Ubaidullah bin Hafs: that `Umar bin Nafi` told him that Nafi`, Maula `Abdullah had heard `Umar saying, I heard Allah's Apostle forbidding Al-Qaza'. 'Ubaidullah added: I said, What is Al-Qaza'? 'Ubaidullah pointed (towards his head) to show us and added, Nafi` said, 'It is when a boy has his head shaved leaving a tuft of hair here and a tuft of hair there. Ubaidullah pointed towards his forehead and the sides of his head. 'Ubaidullah was asked, Does this apply to both girls and boys? He said, I don't know, but Nafi` said, 'The boy.' 'Ubaidullah added, I asked Nafi` again, and he said, 'As for leaving hair on the temples and the back part of the boy's head, there is no harm, but Al-Qaza' is to leave a tuft of hair on his forehead unshaved while there is no hair on the rest of his head, and also to leave hair on either side of his head.'
