Narrated 'Ubada bin As-Samit:

I, along with a group of people, gave the pledge of allegiance to Allah's Apostle. He said, "I take your Pledge on the condition that you (1) will not join partners in worship with Allah, (2) will not steal, (3) will not commit illegal sexual intercourse, (4) will not kill your offspring, (5) will not slander, (6) and will not disobey me when I order you to do good. Whoever among you will abide by his pledge, his reward will be with Allah, and whoever commits any of those sins and receives the punishment in this world, that punishment will be an expiation for his sins and purification;
but if Allah screens him, then it will be up to Allah to punish him if He will or excuse Him, if He will."

حَدَّثَنَا عَبْدُ اللَّهِ الْمُسْنَدِيُّ، حَدَّثَنَا هِشَامٌ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي إِدْرِيسَ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ، قَالَ بَايَعْتُ رَسُولَ اللَّهِ ﷺ فِي رَهْطٍ فَقَالَ " أُبَايِعُكُمْ عَلَى أَنْ لاَ تُشْرِكُوا بِاللَّهِ شَيْئًا، وَلاَ تَسْرِقُوا، وَلاَ تَزْنُوا، وَلاَ تَقْتُلُوا أَوْلاَدَكُمْ، وَلاَ تَأْتُوا بِبُهْتَانٍ تَفْتَرُونَهُ بَيْنَ أَيْدِيكُمْ وَأَرْجُلِكُمْ وَلاَ تَعْصُونِي فِي مَعْرُوفٍ، فَمَنْ وَفَى مِنْكُمْ فَأَجْرُهُ عَلَى اللَّهِ، وَمَنْ أَصَابَ مِنْ ذَلِكَ شَيْئًا فَأُخِذَ بِهِ فِي الدُّنْيَا فَهْوَ لَهُ كَفَّارَةٌ وَطَهُورٌ، وَمَنْ سَتَرَهُ اللَّهُ فَذَلِكَ إِلَى اللَّهِ إِنْ شَاءَ عَذَّبَهُ وَإِنْ شَاءَ غَفَرَ لَهُ ".
