The influence of prayer on human sins

Saying prayer will cancel out our sins. The following koranic verses confirm this view:

1. Keep up prayer at both ends of the days, and at the approach of nigh. Good remove evil deeds. That is a Reminder for such Persons as will be reminded. (11:114)
2. Recite whatever has been revealed to you from the Book, and keep up prayer: prayer restrains one from sexual misconduct and debauchery. Yet mentioning God is even more important, for God knows whatever you produce. (29:45)
3. Man has been created restless. So he panics whenever any evil touches him, and withdraws when some good touches him, except for the prayerful who are constant at their prayers. (70:19-24)
