Sahih al-Bukhari, Volume 8, Book 82, Hadith 813 (USC-MSA) ⓘ

Narrated Ibn `Abbas: When Ma'iz bin Malik came to the Prophet (in order to confess), the Prophet said to him, "Probably you have only kissed (the lady), or winked, or looked at her?" He said, "No, O Allah's Messenger!" The Prophet said, using no euphemism, "Did you have sexual intercourse with her?" The narrator added: At that, (i.e. after his confession) the Prophet ordered that he be stoned (to death).

حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الْجُعْفِيُّ، حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا أَبِي قَالَ، سَمِعْتُ يَعْلَى بْنَ حَكِيمٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ لَمَّا أَتَى مَاعِزُ بْنُ مَالِكٍ النَّبِيَّ صلى الله عليه وسلم قَالَ لَهُ ‏"‏ لَعَلَّكَ قَبَّلْتَ أَوْ غَمَزْتَ أَوْ نَظَرْتَ ‏"‏‏.‏ قَالَ لاَ يَا رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ أَنِكْتَهَا ‏"‏‏.‏ لاَ يَكْنِي‏.‏ قَالَ فَعِنْدَ ذَلِكَ أَمَرَ بِرَجْمِهِ‏.‏
