[Machine] The Messenger of Allah ﷺ said, "The obligatory prayer to the obligatory prayer that follows it is an expiation for what is between them. And the Friday prayer to the Friday prayer, and the fasting of one month to the fasting of another month, which means from the month of Ramadan to the month of Ramadan, is an expiation for what is between them." Then he said afterwards, "Except for three." So I understood that this is something important that he is about to mention. He said, "Except for associating partners with Allah, breaking a deal, and abandoning the Sunnah." I asked, "O Messenger of Allah, we understand what it means to associate partners with Allah, but what does breaking a deal and abandoning the Sunnah mean?" He said, "Breaking a deal is when you make a transaction with someone and then you dispute with them, you confront them with your sword. And abandoning the Sunnah is leaving the congregation."
قَالَ رَسُولُ اللَّهِ ﷺ «الصَّلَاةُ الْمَكْتُوبَةُ إِلَى الصَّلَاةِ الْمَكْتُوبَةِ الَّتِي بَعْدَهَا كَفَّارَةٌ لِمَا بَيْنَهُمَا وَالْجُمُعَةُ إِلَى الْجُمُعَةِ وَالشَّهْرُ إِلَى الشَّهْرِ يَعْنِي مِنْ شَهْرِ رَمَضَانَ إِلَى شَهْرِ رَمَضَانَ كَفَّارَةٌ لِمَا بَيْنَهُمَا» ثُمَّ قَالَ بَعْدَ ذَلِكَ «إِلَّا مِنْ ثَلَاثٍ» فَعَرَفْتُ أَنَّ ذَلِكَ مِنْ أَمْرٍ حَدَثَ فَقَالَ «إِلَّا مِنَ الْإِشْرَاكِ بِاللَّهِ وَنَكْثِ الصَّفْقَةِ وَتَرْكِ السُّنَّةِ» قُلْتُ يَا رَسُولَ اللَّهِ أَمَّا الْإِشْرَاكُ بِاللَّهِ فَقَدْ عَرَفْنَاهُ فَمَا نَكْثُ الصَّفْقَةِ وَتَرْكُ السُّنَّةِ؟ قَالَ أَمَّا نَكْثُ الصَّفْقَةِ أَنْ تَبَايَعَ رَجُلًا بِيَمِينِكَ ثُمَّ تَخْتَلِفَ إِلَيْهِ فُتَقَابِلَهُ بِسَيْفِكَ وَأَمَّا تَرْكُ السُّنَّةِ فَالْخُرُوجُ مِنَ الْجَمَاعَةِ «»
