Sahih Bukhari Volume 8, Book 86, Hadith 6786

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي إِدْرِيسَ الْخَوْلاَنِيِّ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ ـ رضى الله عنه ـ قَالَ كُنَّا عِنْدَ النَّبِيِّ صلى الله عليه وسلم فِي مَجْلِسٍ فَقَالَ ‏"‏ بَايِعُونِي عَلَى أَنْ لاَ تُشْرِكُوا بِاللَّهِ شَيْئًا وَلاَ تَسْرِقُوا، وَلاَ تَزْنُوا ‏"‏‏.‏ وَقَرَأَ هَذِهِ الآيَةَ كُلَّهَا ‏"‏ فَمَنْ وَفَى مِنْكُمْ فَأَجْرُهُ عَلَى اللَّهِ وَمَنْ أَصَابَ مِنْ ذَلِكَ شَيْئًا فَعُوقِبَ بِهِ، فَهْوَ كَفَّارَتُهُ، وَمَنْ أَصَابَ مِنْ ذَلِكَ شَيْئًا، فَسَتَرَهُ اللَّهُ عَلَيْهِ، إِنْ شَاءَ غَفَرَ لَهُ، وَإِنْ شَاءَ عَذَّبَهُ ‏"‏‏

Narrated By 'Ubada bin As-Samit : We were with the Prophet in a gathering and he said, 'Swear allegiance to me that you will not worship anything besides Allah, Will not steal, and will not commit illegal sexual intercourse." And then (the Prophet) recited the whole Verse (i.e. 60:12). The Prophet added, 'And whoever among you fulfills his pledge, his reward is with Allah; and whoever commits something of such sins and receives the legal punishment for it, that will be considered as the expiation for that sin, and whoever commits something of such sins and Allah screens him, it is up to Allah whether to excuse or punish him."
