While I was walking with 'Abdullah at Mina, 'Uthman happened to meet him. He stopped there and began to talk with him. Uthman said to him: Abu 'Abd al-Rahman, should we not marry you to a young girl who may recall to you some of the past of your bygone days; thereupon he said: If you say so, Messenger of Allah ﷺ said: 0 young men, those among you who can support a wife should marry, for it restrains eyes from casting (evil glances). and preserves one from immorality; but those who cannot should devote themselves to fasting for it is a means of controlling sexual desire. (Using translation from Muslim 1400a)
عَنْ عَلْقَمَةَ قَالَكُنْتُ أَمْشِي مَعَ عَبْدِ اللهِ بِمِنًى فَلَقِيَهُ عُثْمَانُ فَقَامَ مَعَهُ يُحَدِّثُهُ فَقَالَ لَهُ عُثْمَانُ يَا أَبَا عَبْدِ الرَّحْمَنِ أَلَا نُزَوِّجُكَ جَارِيَةً شَابَّةً لَعَلَّهَا أَنْ تُذَكِّرَكَ مَا مَضَى مِنْ زَمَانِكَ؟ فَقَالَ عَبْدُ اللهِ أَمَا لَئِنْ قُلْتَ ذَاكَ لَقَدْ قَالَ لَنَا رَسُولُ اللهِ ﷺ يَا مَعْشَرَ الشَّبَابِ مَنِ اسْتَطَاعَ مِنْكُمُ الْبَاءَةَ فَلْيَتَزَوَّجْ فَإِنَّهُ أَغَضُّ لِلْبَصَرِ وَأَحْصَنُ لِلْفَرْجِ وَمَنْ لَمْ يَسْتَطِعْ فَعَلَيْهِ بِالصَّوْمِ فَإِنَّهُ لَهُ وِجَاءٌ
