صَحِيحُ مُسْلِمٍ
Sahih Muslim 233b
The Book of Purification
The five daily prayers, from one Jumu`ah to the next, and from one Ramadan to the next, are an expiation for whatever (sins) come in between, so long as one avoids major sins
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 .
Abu Huraira reported that the Messenger of Allah (ﷺ) 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.
