We used to fight in the holy battles in the company of the Prophet ﷺ and we had no wives with us. So we said, "O Messenger of Allah ﷺ! Shall we get castrated?" The Prophet ﷺ forbade us to do so.
كُنَّا نَغْزُو مَعَ النَّبِيِّ ﷺ وَلَيْسَ لَنَا نِسَاءٌ فَقُلْنَا يَا رَسُولَ اللَّهِ أَلاَ نَسْتَخْصِي فَنَهَانَا عَنْ ذَلِكَ
[Machine] We used to accompany the Prophet ﷺ in battles while we were young men and we did not have any wives. So, we asked, "O Messenger of Allah, should we not get ourselves castrated?" He forbade us from doing so.
كُنَّا نَغْزُو مَعَ النَّبِيِّ ﷺ وَنَحْنُ شَبَابٌوَلَيْسَ لَنَا نِسَاءٌ فَقُلْنَا يَا رَسُولَ اللهِ أَلَا نَسْتَخْصِي؟ فَنَهَانَا عَنْ ذَلِكَ
We used to fight in the holy battles in the company of the Prophet ﷺ and we had no wives with us. So we said, "O Messenger of Allah ﷺ! Shall we get castrated?" The Prophet ﷺ forbade us to do so. (Using translation from Bukhārī 5071)
كُنَّا نَغْزُو مَعَ رَسُولِ اللهِ ﷺ لَيْسَ لَنَا نِسَاءٌ فَقُلْنَا يَا رَسُولَ اللهِ أَلَا نَسْتَخْصِي؟ فَنَهَانَا عَنْ ذَلِكَ
