The Book of Marriage
16/1. Chapter:
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
Sahih Muslim
وَحَدَّثَنِي أَبُو عِمْرَانَ، مُحَمَّدُ بْنُ جَعْفَرِ بْنِ زِيَادٍ حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ ابْنِ، شِهَابٍ الزُّهْرِيِّ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، قَالَ سَمِعْتُ سَعْدًا، يَقُولُ رُدَّ عَلَى عُثْمَانَ بْنِ مَظْعُونٍ التَّبَتُّلُ وَلَوْ أُذِنَ لَهُ لاَخْتَصَيْنَا .
Sa'id b. al-Musayyib reported: I heard Sa'd (b. Abi Waqqas) saying that the idea of 'Uthman b. Maz'un for living in celibacy was rejected (by the Holy Prophet), and if he had been given permission they would have got themselves castrated.
