'Ubadah bin As-Samit (RAA) narrated that the Messenger of Allah (ﷺ) said:

"Receive from me (this revelation), receive from me (this revelation). Allah has ordained a way for those women (unmarried females who committed adultery). When an unmarried man, commits adultery with an unmarried woman, they should receive one hundred lashes and be exiled for a year. If they (fornicate while they) were married, they shall receive hundred lashes and be stoned to death. Reported by Muslim.

وَعَنْ عُبَادَةَ بْنِ اَلصَّامِتِ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ خُذُوا عَنِّي, خُذُوا عَنِّي, فَقَدْ جَعَلَ اَللَّهُ لَهُنَّ سَبِيلاً, اَلْبِكْرُ بِالْبِكْرِ جَلْدُ مِائَةٍ, وَنَفْيُ سَنَةٍ, وَالثَّيِّبُ بِالثَّيِّبِ جَلْدُ مِائَةٍ, وَالرَّجْمُ } رَوَاهُ مُسْلِمٌ.‏ [1]‏ .‏
