[Machine] From the Prophet ﷺ , he said: "The prayer from one prayer to the next is an expiation (for the sins committed between them), and Friday prayer to Friday prayer is an expiation, and Ramadan to Ramadan is an expiation, except for sins that are major. He said: So we knew that it is an order except for polytheism with Allah, breaking a deal, and abandoning the Sunnah. He said: We said, O Messenger of Allah, we know what polytheism with Allah is, so what is breaking a deal and abandoning the Sunnah? He said: Breaking a deal is when you sell something to someone and then you fight him with your sword, and abandoning the Sunnah is leaving the congregation."
عَنِ النَّبِيِّ ﷺ قَالَ الصَّلَاةُ إِلَى الصَّلَاةِ الَّتِي قَبْلَهَا كَفَّارَةٌ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ الَّتِي قَبْلَهَا كَفَّارَةٌ وَالشَّهْرُ إِلَى الشَّهْرِ الَّذِي قَبْلَهُ كَفَّارَةٌ إِلَّا مِنْ ثَلَاثٍ قَالَ فَعَرَفْنَا أَنَّهُ أَمْرٌ حَدَثَ إِلَّا مِنَ الشِّرْكِ بِاللهِ وَنَكْثِ الصَّفْقَةِ وَتَرْكِ السُّنَّةِ قَالَ قُلْنَا يَا رَسُولَ اللهِ هَذَا الشِّرْكُ بِاللهِ قَدْ عَرَفْنَاهُ فَمَا نَكْثُ الصَّفْقَةِ وَتَرْكُ السُّنَّةِ؟ قَالَ أَمَّا نَكْثُ الصَّفْقَةِ فَأَنْ تُعْطِيَ رَجُلًا بَيْعَتَكَ ثُمَّ تُقَاتِلَهُ بِسَيْفِكِ وَأَمَّا تَرْكُ السُّنَّةِ فَالْخُرُوجُ مِنَ الْجَمَاعَةِ
