Abu Huraira reported that the Messenger of Allah said: The five (daily) prayers and one Friday prayer to (the next) Friday prayer are expiations (for the sins committed in the intervals) between them.
حَدَّثَنِي نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، أَخْبَرَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا هِشَامٌ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الصَّلَوَاتُ الْخَمْسُ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ كَفَّارَاتٌ لِمَا بَيْنَهُنَّ " .
