وَعَنْ عَطِيَّةَ اَلْقُرَظِيِّ رضى الله عنه
قَالَ: «عُرِضْنَا عَلَى اَلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمَ قُرَيْظَةَ، فَكَانَ مَنْ أَنْبَتَ قُتِلَ، وَمَنْ لَمْ يُنْبِتْ خُلِّيَ سَبِيلُهُ، فَكُنْتُ فِيمَنْ لَمْ يُنْبِتْ فَخُلِّيَ سَبِيلِي»
We were brought before the Prophet (sallallahu alayhi wa sallam) on the day of Quraizah. Those who had began to grow hair (on their private parts) were killed, while who had not, were set free. I was among those who had not begun to grow hair, so I was set free.
