عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «يَا مَعْشَرَ الشَّبَابِ مَنِ اسْتَطَاعَ مِنْكُمُ الْبَاءَةَ فَلْيَتَزَوَّجْ فَإِنَّهُ أَغَضُّ لِلْبَصَرِ وَأَحْصَنُ لِلْفَرْجِ وَمَنْ لَمْ يَسْتَطِعْ فَعَلَيْهِ بِالصَّوْمِ فَإِنَّهُ لَهُ وِجَاءٌ»

'Abdallah b. Mas'ud reported God’s Messenger as saying, “Young man, those of you who can support a wife should marry, for it keeps you from looking at strange women and preserves you from immorality; but those who cannot should devote themselves to fasting, for it is a means of suppressing sexual desire.”* (Bukhari and Muslim.) * Waja' has been translated freely above. It means castration.
