حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا مَعْمَرٌ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى صَبِيًّا قَدْ حُلِقَ بَعْضُ شَعَرِهِ وَتُرِكَ بَعْضُهُ فَنَهَى عَنْ ذَلِكَ وَقَالَ احْلِقُوا كُلَّهُ أَوْ اتْرُكُوا كُلَّهُ
مسند امام احمد بن حنبل · Hadith 5615
It was narrated from 'Ibn 'Umar that the Prophet (PBUH) saw a boy who had part of his head shaved and part of it was left. He forbade that and said: "Shave all of it or leave all of it.”
