Sahih Bukhari Volume 9, Book 93, Hadith 7169

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنِي اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، وَسَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ أَتَى رَجُلٌ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهْوَ فِي الْمَسْجِدِ فَنَادَاهُ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي زَنَيْتُ‏.‏ فَأَعْرَضَ عَنْهُ‏.‏ فَلَمَّا شَهِدَ عَلَى نَفْسِهِ أَرْبَعًا قَالَ ‏"‏ أَبِكَ جُنُونٌ ‏"‏‏.‏ قَالَ لاَ‏.‏ قَالَ ‏"‏ اذْهَبُوا بِهِ فَارْجُمُوهُ ‏"‏‏

Narrated By Abu Huraira : A man came to Allah's Apostle while he was in the mosque, and called him, saying, "O Allah's Apostle! I have committed illegal sexual intercourse." The Prophet turned his face to the other side, but when the man gave four witnesses against himself, the Prophet said to him, "Are you mad?" The man said, "No." So the Prophet said (to his companions), "Take him away and stone him to death."
