[Machine] That the Messenger of Allah ﷺ prohibited him from exchanging his skill, even if he had allowed it, we would have made an exception.  

أَنْ يَتَبَتَّلَ فَنَهَاهُ رَسُولُ اللهِ ﷺ عَنْ ذَلِكَ وَلَوْ أَجَازَ لَهُ لَاخْتَصَيْنَا  

The above tradition has been narrated on the same authority through different chains of transmitters. (Using translation from Muslim 1831b)   

عَنْ أَبِي الْيَمَانِ  

We used to participate in the holy battles led by Messenger of Allah ﷺ and we had nothing (no wives) with us. So we said, "Shall we get ourselves castrated?" He forbade us that and then allowed us to marry women with a temporary contract (2) and recited to us: -- 'O you who believe ! Make not unlawful the good things which Allah has made lawful for you, but commit no transgression.' (5.87) (Using translation from Bukhārī 5075)   

سَمِعْتُ عَبْدَ اللهِ يَقُولُ كُنَّا نَغْزُو مَعَ رَسُولِ اللهِ ﷺ لَيْسَ لَنَا نِسَاءٌ فَقُلْنَا أَلَا نَسْتَخْصِي فَنَهَانَا عَنْ ذَلِكَ رَسُولُ اللهِ ﷺ ثُمَّ رَخَّصَ لَنَا أَنْ نَنْكِحَ الْمَرْأَةَ بِالثَّوْبِ ثُمَّ قَرَأَ عَلَيْنَا {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُحَرِّمُوا طَيِّبَاتِ مَا أَحَلَّ اللهُ لَكُمْ وَلَا تَعْتَدُوا إِنَّ اللهَ لَا يُحِبُّ الْمُعْتَدِينَ} [المائدة 87]  

[Machine] I came to the Messenger of Allah ﷺ and said, "O Messenger of Allah, I am a young man and I fear falling into sin, and I cannot find a woman to marry. Give me permission to restrain myself." He remained silent. Then I repeated the same statement to him, and he remained silent. Then I repeated the same statement to him, and he said, "O Abu Huraira, the pen has dried up with what you are insisting on. Either restrain yourself or marry."  

أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ إِنِّي رَجُلٌ شَابٌّ وَإِنِّي أَخَافُ عَلَى نَفْسِي الْعَنَتَ وَلَا أَجِدُ مَا أَتَزَوَّجُ النِّسَاءَ فَأْذَنْ لِي أَنْ أَخْتَصِيَ قَالَ فَسَكَتَ عَنِّي ثُمَّ قُلْتُ لَهُ مِثْلَ ذَلِكَ فَسَكَتَ عَنِّي ثُمَّ قُلْتُ لَهُ مِثْلَ ذَلِكَ فَقَالَ رَسُولُ اللهِ ﷺ يَا أَبَا هُرَيْرَةَ قَدْ جَفَّ الْقَلَمُ بِمَا أَنْتَ لَاقٍ فَاخْتَصِ عَلَى ذَلِكَ أَوْ دَعْ
