Narrated Zaid bin Khalid:
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ ، حَدَّثَنَا اللَّيْثُ ، عَنْ عُقَيْلٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ ، عَنْ زَيْدِ بْنِ خَالِدٍ ـ رضى الله عنه ـ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ أَمَرَ فِيمَنْ زَنَى وَلَمْ يُحْصِنْ بِجَلْدِ مِائَةٍ وَتَغْرِيبِ عَامٍ.
Allah's Messenger (ﷺ) ordered that an unmarried man who committed illegal sexual intercourse be scourged one hundred lashes and sent into exile for one year.
