وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الصَّلَوَاتُ الْخَمْسُ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ وَرَمَضَانُ إِلَى رَمَضَانَ مُكَفِّرَاتٌ لَمَّا بَيْنَهُنَّ إِذَا اجْتُنِبَتِ الْكَبَائِر»
Abu Hurayrah reported God’s Messenger as saying, “The five prayers, Friday to Friday and Ramadan to Ramadan make atonement for what has happened since the previous one when major sins have been avoided.”
