The Messenger of Allah ﷺ said: Five prayers and from one Friday prayer to (the next) Friday prayer is an expiation (of the sins committed in between their intervals) if major sins are not committed.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الصَّلاَةُ الْخَمْسُ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ كَفَّارَةٌ لِمَا بَيْنَهُنَّ مَا لَمْ تُغْشَ الْكَبَائِرُ
