Sahih Muslim 1400
Sahih Muslim · Book 16: The Book of Marriage · Marriage is recommended for the one who desires it and can afford it, and the one who cannot afford it should distract himself by fasting
'Abd al-Rahman b. Yazid reported on the authority of Abdullah:
حَدَّثَنِي عَبْدُ اللَّهِ بْنُ سَعِيدٍ الأَشَجُّ ، حَدَّثَنَا وَكِيعٌ ، حَدَّثَنَا الأَعْمَشُ ، عَنْ عُمَارَةَ بْنِ، عُمَيْرٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ ، عَنْ عَبْدِ اللَّهِ ، قَالَ دَخَلْنَا عَلَيْهِ وَأَنَا أَحْدَثُ الْقَوْمِ، بِمِثْلِ حَدِيثِهِمْ وَلَمْ يَذْكُرْ فَلَمْ أَلْبَثْ حَتَّى تَزَوَّجْتُ .
We went to him, and I was the youngest of all (of us), but he did not mention:" I lost no time in marrying."
