حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا مَعْمَرٌ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنْ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَی صَبِيًّا قَدْ حُلِقَ بَعْضُ شَعْرِهِ وَتُرِکَ بَعْضُهُ فَنَهَاهُمْ عَنْ ذَلِکَ وَقَالَ احْلِقُوهُ کُلَّهُ أَوْ اتْرُکُوهُ کُلَّهُ

Narrated Abdullah ibn Umar: The Prophet ﷺ saw a boy with part of his head shaved and part left unshaven. He forbade them to do that, saying: Shave it all or leave it all.
