باب اسْتِحْبَابِ النِّكَاحِ لِمَنْ تَاقَتْ نَفْسُهُ إِلَيْهِ وَوَجَدَ مُؤْنَةً وَاشْتِغَالِ مَنْ عَجَزَ عَنِ الْمُؤَنِ بِالصَّوْمِ
Sahih Muslim 1400 b

'Alqama reported:

While I was going along with 'Abdullah b. Ma'sud (Allah he pleased with him) in Mina, 'Uthman b. 'Affan (Allah be pleased with him) happened to meet him and said: Come here, Abu 'Abd al-Rahman (kunya of Abdullah b. Mas'ud), and he isolated him (from me), and when 'Abdullah (b. Mas'ud) saw that there was no need (for this privacy), he said to me: 'Alqama, come on, and so I went there. (Then) 'Uthman said to him: Abu Abd al-Rahman, should we not marry you to a virgin girl that your past may be recalled to your mind? 'Abdullah said: If you say so, the rest of the hadith is the same as narrated above.
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، قَالَ إِنِّي لأَمْشِي مَعَ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ بِمِنًى إِذْ لَقِيَهُ عُثْمَانُ بْنُ عَفَّانَ فَقَالَ هَلُمَّ يَا أَبَا عَبْدِ الرَّحْمَنِ قَالَ فَاسْتَخْلاَهُ فَلَمَّا رَأَى عَبْدُ اللَّهِ أَنْ لَيْسَتْ لَهُ حَاجَةٌ - قَالَ - قَالَ لِي تَعَالَ يَا عَلْقَمَةُ - قَالَ - فَجِئْتُ فَقَالَ لَهُ عُثْمَانُ أَلاَ نُزَوِّجُكَ يَا أَبَا عَبْدِ الرَّحْمَنِ جَارِيَةً بِكْرًا لَعَلَّهُ يَرْجِعُ إِلَيْكَ مِنْ نَفْسِكَ مَا كُنْتَ تَعْهَدُ فَقَالَ عَبْدُ اللَّهِ لَئِنْ قُلْتَ ذَاكَ ‏.‏ فَذَكَرَ بِمِثْلِ حَدِيثِ أَبِي مُعَاوِيَةَ ‏.‏
