Sahih Bukhari Volume 7, Book 68, Hadith 5273

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، وَسَعِيدُ بْنُ الْمُسَيَّبِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ أَتَى رَجُلٌ مِنْ أَسْلَمَ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهْوَ فِي الْمَسْجِدِ فَنَادَاهُ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ الأَخِرَ قَدْ زَنَى ـ يَعْنِي نَفْسَهُ ـ فَأَعْرَضَ عَنْهُ فَتَنَحَّى لِشِقِّ وَجْهِهِ الَّذِي أَعْرَضَ قِبَلَهُ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ الأَخِرَ قَدْ زَنَى فَأَعْرَضَ عَنْهُ فَتَنَحَّى لِشِقِّ وَجْهِهِ الَّذِي أَعْرَضَ قِبَلَهُ فَقَالَ لَهُ ذَلِكَ فَأَعْرَضَ عَنْهُ فَتَنَحَّى لَهُ الرَّابِعَةَ، فَلَمَّا شَهِدَ عَلَى نَفْسِهِ أَرْبَعَ شَهَادَاتٍ دَعَاهُ فَقَالَ ‏"‏ هَلْ بِكَ جُنُونٌ ‏"‏‏.‏ قَالَ لاَ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ اذْهَبُوا بِهِ فَارْجُمُوهُ ‏"‏‏.‏ وَكَانَ قَدْ أُحْصِنَ‏

Narrated By Abu Huraira : A man from Bani Aslam came to Allah's Apostle while he was in the mosque and called (the Prophet) saying, "O Allah's Apostle! I have committed illegal sexual intercourse." On that the Prophet turned his face from him to the other side, whereupon the man moved to the side towards which the Prophet had turned his face, and said, "O Allah's Apostle! I have committed illegal sexual intercourse." The Prophet turned his face (from him) to the other side whereupon the man moved to the side towards which the Prophet had turned his face, and repeated his statement. The Prophet turned his face (from him) to the other side again. The man moved again (and repeated his statement) for the fourth time. So when the man had given witness four times against himself, the Prophet called him and said, "Are you insane?" He replied, "No." The Prophet then said (to his companions), "Go and stone him to death." The man was a married one.
