11:114
وَأَقِمِ ٱلصَّلَوٰةَ طَرَفَىِ ٱلنَّهَارِ وَزُلَفًا مِّنَ ٱلَّيْلِ ۚ إِنَّ ٱلْحَسَنَـٰتِ يُذْهِبْنَ ٱلسَّيِّـَٔاتِ ۚ ذَٰلِكَ ذِكْرَىٰ لِلذَّٰكِرِينَ
wa-aqimi l-ṣalata ṭarafayi l-nahāri wazulafan mina al-layli inna l-ḥasanāti yudh'hib'na l-sayiāti dhālika dhik'rā lildhākirīna
[Prophet], keep up the prayer at both ends of the day, and during parts of the night, for good things drive bad away- this is a reminder for those who are aware.
And perform As-Salât (Iqâmat-as-Salât ), at the two ends of the day and in some hours of the night [i.e. the five compulsory Salât (prayers)]. Verily, the good deeds remove the evil deeds (i.e. small sins). That is a reminder (an advice) for the mindful (those who accept advice).
