Sahih Muslim, 1694 c
sahih

This hadith has been narrated on the authority of Dawud with the same chain of transmitters but with this variation that in the hadith narrated by Sufyan (the words are):

" He made a confession of having committed adultery, thrice."

وَحَدَّثَنَا سُرَيْجُ بْنُ يُونُسَ، حَدَّثَنَا يَحْيَى بْنُ زَكَرِيَّاءَ بْنِ أَبِي زَائِدَةَ، ح وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا مُعَاوِيَةُ بْنُ هِشَامٍ، حَدَّثَنَا سُفْيَانُ، كِلاَهُمَا عَنْ دَاوُدَ، بِهَذَا الإِسْنَادِ ‏.‏ بَعْضَ هَذَا الْحَدِيثِ ‏.‏ غَيْرَ أَنَّ فِي حَدِيثِ سُفْيَانَ فَاعْتَرَفَ بِالزِّنَى ثَلاَثَ مَرَّاتٍ ‏.‏
