Sunan Ibn Majah, Book 5, Hadith 1139 (In-Book) ⓘ
It was narrated from Abu Hurairah that the Messenger of Allah said: “From one Friday to the next is an expiation for whatever was committed in between, so long as one does not commit any major sin.”
حَدَّثَنَا مُحْرِزُ بْنُ سَلَمَةَ الْعَدَنِيُّ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " الْجُمُعَةُ إِلَى الْجُمُعَةِ كَفَّارَةُ مَا بَيْنَهُمَا مَا لَمْ تُغْشَ الْكَبَائِرُ " .
