HOW TO RANSOM YOUR SINS H 1062 "For every Muslim who makes his ablution diligently when the obligatory prayer arrives and perfects its due in humility and bowing, this will ransom his previous sins as long as he has not committed a major sin; and this is for ever." R 1062 Muslim with a chain up to Othman son of Affan who related that he heard the Messenger of Allah, praise and peace be upon him, said this.
1046- وعن عثمان بن عفان رضي الله عنه ، قَالَ : سَمِعْتُ رسول الله صلى الله عليه وآله وسلم ، يقول : "مَا مِنْ امْرِئٍ مُسْلِمٍ تَحْضُرُهُ صَلاَةٌ مَكْتُوبَةٌ فَيُحْسِنُ وُضُوءها ؛ وَخُشُوعَهَا، وَرُكُوعَهَا ، إِلاَّ كَانَتْ كَفَّارَةً لِمَا قَبْلَهَا مِنَ الذُّنُوب مَا لَمْ تُؤتَ كَبِيرةٌ ، وَذلِكَ الدَّهْرَ كُلَّهُ" رواه مسلم .
