It was narrated from Jabir bin Abdullah that:

a man from Aslam came to the Prophet and confessed to committing Zina, and he turned away from him. He admitted it again, and he turned away from him. He admitted it again, and he turned away from him. Then when he had testified against himself four times, the Prophet ﷺ said: "Are your crazy?" He said: "No." He said: "Have you been marred?" he said: "Yes." So the Prophet ordered that he be stoned. When the stones struck him, he ran away, but they caught up with him and stoned him and he died. Then the Prophet spoke well of him but he did not pray for him. (Shih)

أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى، وَنُوحُ بْنُ حَبِيبٍ، قَالاَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ حَدَّثَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ رَجُلاً، مِنْ أَسْلَمَ جَاءَ إِلَى النَّبِيِّ ﷺ فَاعْتَرَفَ بِالزِّنَا فَأَعْرَضَ عَنْهُ ثُمَّ اعْتَرَفَ فَأَعْرَضَ عَنْهُ ثُمَّ اعْتَرَفَ فَأَعْرَضَ عَنْهُ حَتَّى شَهِدَ عَلَى نَفْسِهِ أَرْبَعَ مَرَّاتٍ فَقَالَ النَّبِيُّ ﷺ " أَبِكَ جُنُونٌ " . قَالَ لاَ . قَالَ " أَحْصَنْتَ " . قَالَ نَعَمْ . فَأَمَرَ بِهِ النَّبِيُّ ﷺ فَرُجِمَ فَلَمَّا أَذْلَقَتْهُ الْحِجَارَةُ فَرَّ فَأُدْرِكَ فَرُجِمَ فَمَاتَ فَقَالَ لَهُ النَّبِيُّ ﷺ خَيْرًا وَلَمْ يُصَلِّ عَلَيْهِ .
