Perform As-Salat (Iqamat-as-Salat) from mid-day till the darkness of the night (i.e. the Zuhr, 'Asr, Maghrib, and 'Isha' prayers), and recite the Quran in the early dawn (i.e. the morning prayer). Verily, the recitation of the Quran in the early dawn is ever witnessed (attended by the angels in charge of mankind of the day and the night). 78 And of the night - keep the vigil therein, as an act of supererogation for thee; belike thy Lord will raise thee up in a station praised. 79 And say: My Lord! Cause me to come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 And say: "Truth (i.e. Islamic Monotheism or this Quran or Jihad against polytheists) has come and Batil (falsehood, i.e. Satan or polytheism, etc.) has vanished. Surely! Batil is ever bound to vanish." 81 We send down in the Quran that which is healing and a mercy to those who believe; as for the evil-doers, it only increases their loss. 82 And when We make life pleasant unto man, he turneth away and is averse; and when ill toucheth him he is in despair. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
