وَأَقِمِ الصَّلاَةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِّنَ اللَّيْلِ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّيِّئَاتِ ذَلِكَ ذِكْرَى لِلذَّاكِرِينَ
And establish prayer at the two ends of the day and at the approach of the night. Indeed, good deeds remove bad deeds. That is a reminder for those who remember.
