It Is Disliked To Shave Part Of The Head And Leave Part
Sahih Muslim
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنِي يَحْيَى، - يَعْنِي ابْنَ سَعِيدٍ - عَنْ عُبَيْدِ اللَّهِ، أَخْبَرَنِي عُمَرُ بْنُ نَافِعٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْقَزَعِ . قَالَ قُلْتُ لِنَافِعٍ وَمَا الْقَزَعُ قَالَ يُحْلَقُ بَعْضُ رَأْسِ الصَّبِيِّ وَيُتْرَكُ بَعْضٌ .
Ibn Umar reported that Allah's Messenger (ﷺ) forbade Qaza. I said to Nafi: What is Qaza'? He said: This means having a part of a boy's head shaved and leaving a part unshaven.
