'Alqama reported: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, Allah's Messenger (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.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى التَّمِيمِيُّ، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَمُحَمَّدُ بْنُ الْعَلاَءِ الْهَمْدَانِيُّ جَمِيعًا عَنْ أَبِي مُعَاوِيَةَ، - وَاللَّفْظُ لِيَحْيَى أَخْبَرَنَا أَبُو مُعَاوِيَةَ، - عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، قَالَ كُنْتُ أَمْشِي مَعَ عَبْدِ اللَّهِ بِمِنًى فَلَقِيَهُ عُثْمَانُ فَقَامَ مَعَهُ يُحَدِّثُهُ فَقَالَ لَهُ عُثْمَانُ يَا أَبَا عَبْدِ الرَّحْمَنِ أَلاَ نُزَوِّجُكَ جَارِيَةً شَابَّةً لَعَلَّهَا تُذَكِّرُكَ بَعْضَ مَا مَضَى مِنْ زَمَانِكَ . قَالَ فَقَالَ عَبْدُ اللَّهِ لَئِنْ قُلْتَ ذَاكَ لَقَدْ قَالَ لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم " يَا مَعْشَرَ الشَّبَابِ مَنِ اسْتَطَاعَ مِنْكُمُ الْبَاءَةَ فَلْيَتَزَوَّجْ فَإِنَّهُ أَغَضُّ لِلْبَصَرِ وَأَحْصَنُ لِلْفَرْجِ وَمَنْ لَمْ يَسْتَطِعْ فَعَلَيْهِ بِالصَّوْمِ فَإِنَّهُ لَهُ وِجَاءٌ " .
