While I was walking with ʿAbdullah he said, "We were in the company of the Prophet ﷺ and he said, 'He who can afford to marry should marry, because it will help him refrain from looking at other women, and save his private parts from committing illegal sexual relation; and he who cannot afford to marry is advised to fast, as fasting will diminish his sexual power."  

بَيْنَا أَنَا أَمْشِي مَعَ عَبْدِ اللَّهِ ؓ فَقَالَ كُنَّا مَعَ النَّبِيِّ ﷺ فَقَالَ مَنِ اسْتَطَاعَ الْبَاءَةَ فَلْيَتَزَوَّجْ فَإِنَّهُ أَغَضُّ لِلْبَصَرِ وَأَحْصَنُ لِلْفَرْجِ وَمَنْ لَمْ يَسْتَطِعْ فَعَلَيْهِ بِالصَّوْمِ فَإِنَّهُ لَهُ وِجَاءٌ
