Hud - ১১:১১৪

وَأَقِمِ الصَّلاَةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِّنَ اللَّيْلِ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّـيِّئَاتِ ذَلِكَ ذِكْرَى لِلذَّاكِرِينَ
[11:114]
And keep up prayer in the two parts of the day and in the first hours of the night; surely good deeds take away evil deeds this is a reminder to the mindful.
And establish regular prayers at the two ends of the day and at the approaches of the night: For those things, that are good remove those that are evil: Be that the word of remembrance to those who remember (their Lord):
Establish worship at the two ends of the day and in some watches of the night. Lo! good deeds annul ill-deeds. This is reminder for the mindful.
