Sunan Ibn Majah Book 20, Hadith 2554

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبَّادُ بْنُ الْعَوَّامِ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ جَاءَ مَاعِزُ بْنُ مَالِكٍ إِلَى النَّبِيِّ صلى الله عليه وسلم ‏.‏ فَقَالَ إِنِّي قَدْ زَنَيْتُ ‏.‏ فَأَعْرَضَ عَنْهُ ثُمَّ قَالَ إِنِّي قَدْ زَنَيْتُ فَأَعْرَضَ عَنْهُ ‏.‏ ثُمَّ قَالَ إِنِّي زَنَيْتُ ‏.‏ فَأَعْرَضَ عَنْهُ ‏.‏ ثُمَّ قَالَ قَدْ زَنَيْتُ ‏.‏ فَأَعْرَضَ عَنْهُ حَتَّى أَقَرَّ أَرْبَعَ مَرَّاتٍ فَأَمَرَ بِهِ أَنْ يُرْجَمَ ‏.‏ فَلَمَّا أَصَابَتْهُ الْحِجَارَةُ أَدْبَرَ يَشْتَدُّ فَلَقِيَهُ رَجُلٌ بِيَدِهِ لَحْىُ جَمَلٍ فَضَرَبَهُ فَصَرَعَهُ فَذُكِرَ لِلنَّبِيِّ صلى الله عليه وسلم فِرَارُهُ حِينَ مَسَّتْهُ الْحِجَارَةُ قَالَ ‏ "‏ فَهَلاَّ تَرَكْتُمُوهُ ‏"‏ ‏.‏

It was narrated that Abu Hurairah said:“Ma`iz bin Malik came to the Prophet (ﷺ) and said: 'I have committed fornication,' and he (the Prophet (ﷺ)) turned away from him. He said: 'I have committed fornication,' and he turned away from him. Then, he said: I have committed fornication, and he turned away from him, until when he had confessed four times, he ordered that he should be stoned. When he was being struck with the stones, he ran away, but a man caught up with him who had a camel's jawbone in his hand; he struck him and he fell down. The Prophet (ﷺ) was told about how he fled when the stones hit him and he said: 'Why did you not let him be?'”
