HOW TO HAVE YOUR SINS FORGIVEN H 131 "The five daily prayers, Friday to Friday and (the fasting of) Ramadan to Ramadan annul whatever (sin) may be between them so long as the major sins are avoided." R 131 Muslim with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
130- الرابع عشر : عَنْهُ ، عن رَسُول الله صلى الله عليه وآله وسلم ، قَالَ : "الصَّلَوَاتُ الخَمْسُ ، وَالجُمُعَةُ إِلَى الجُمُعَةِ ، وَرَمَضَانُ إِلَى رَمَضَانَ مُكَفِّراتٌ لِمَا بَيْنَهُنَّ إِذَا اجْتُنِبَتِ الكَبَائِرُ" رواه مسلم .
