صحيح البخاري#5066Sahihحَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي عُمَارَةُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ، قَالَ دَخَلْتُ مَعَ عَلْقَمَةَ وَالأَسْوَدِ عَلَى عَبْدِ اللَّهِ فَقَالَ عَبْدُ اللَّهِ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم شَبَابًا لاَ نَجِدُ شَيْئًا فَقَالَ لَنَا رَسُولُ اللَّهُ صلى الله عليه وسلم " يَا مَعْشَرَ الشَّبَابِ مَنِ اسْتَطَاعَ الْبَاءَةَ فَلْيَتَزَوَّجْ، فَإِنَّهُ أَغَضُّ لِلْبَصَرِ، وَأَحْصَنُ لِلْفَرْجِ، وَمَنْ لَمْ يَسْتَطِعْ فَعَلَيْهِ بِالصَّوْمِ، فَإِنَّهُ لَهُ وِجَاءٌ ".
Narrated `Abdullah:We were with the Prophet (ﷺ) while we were young and had no wealth. So Allah's Messenger (ﷺ) said, "O young people! Whoever among you can marry, should marry, because it helps him lower his gaze and guard his modesty (i.e. his private parts from committing illegal sexual intercourse etc.), and whoever is not able to marry, should fast, as fasting diminishes his sexual power
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
