وَعَنْهُ أَيْضًا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((الصَّلَاةُ إِلَى الصَّلَاةِ الَّتِي قَبْلَهَا كَفَّارَةٌ، وَالْجُمْعَةُ إِلَى الْجُمُعَةِ الَّتِي قَبْلَهَا كَفَّارَةٌ، وَالشَّهْرُ إِلَى الشَّهْرِ الَّذِي قَبْلَهُ كَفَّارَةٌ إِلَّا مِنْ ثَلَاثٍ)) قَالَ: فَعَرَفْنَا أَنَّهُ أَمْرٌ حَدَثَ، ((إِلَّا مِنَ الشِّرْكِ بِاللَّهِ وَنَكْثِ الصَّفْقَةِ وَتَرْكِ السُّنَّةِ)) قَالَ: ((أَمَّا نَكْثُ الصَّفْقَةِ فَأَنْ تُعْطِيَ رَجُلًا بَيْعَتَكَ ثُمَّ تُقَاتِلَهُ بِسَيْفِكَ، وَأَمَّا تَرْكُ السُّنَّةِ فَالْخُرُوجُ مِنَ الْجَمَاعَةِ))
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Prayer is an expiation until the next prayer, Friday is an expiation until the next Friday, and the month of Ramadan is an expiation until the next month, except for three sins. We realized that a new situation had arisen, except associating partners with Allah, breaking a covenant, and abandoning the Sunnah. Then he (peace and blessings be upon him) said: Breaking a covenant is that you make a pact with someone, but then you start fighting him with the sword, and abandoning the Sunnah means separating from the congregation.
