صحيح البخاري#6831Sahihحَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، أَخْبَرَنَا ابْنُ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَأْمُرُ فِيمَنْ زَنَى وَلَمْ يُحْصَنْ جَلْدَ مِائَةٍ وَتَغْرِيبَ عَامٍ. قَالَ ابْنُ شِهَابٍ وَأَخْبَرَنِي عُرْوَةَ بْنُ الزُّبَيْرِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، غَرَّبَ، ثُمَّ لَمْ تَزَلْ تِلْكَ السُّنَّةَ.
Narrated Zaid bin Khalid Al-Juhani:I heard the Prophet (ﷺ) ordering that an unmarried person guilty of illegal sexual intercourse be flogged one-hundred stripes and be exiled for one year. `Umar bin Al-Khattab also exiled such a person, and this tradition is still valid
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.
