Establish worship at the going down of the sun until the dark of night, and (the recital of) the Qur'an at dawn. Lo! (the recital of) the Qur'an at dawn is ever witnessed. 78 And in some parts of the night (also) offer the Salat (prayer) with it (i.e. recite the Quran in the prayer), as an additional prayer (Tahajjud optional prayer Nawafil) for you (O Muhammad SAW). It may be that your Lord will raise you to Maqaman Mahmuda (a station of praise and glory, i.e. the highest degree in Paradise!). 79 And say [in thy prayer]: "O my Sustainer! Cause me to enter [upon whatever I may do] in a manner true and sincere, and cause me to leave [it] in a manner true and sincere, and grant me, out of Thy grace, sustaining strength!" 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 What We have sent down of the Qur'an is a healing and a grace for the faithful, and adds only loss for the sinners. 82 And when We bestow Our Grace on man (the disbeliever), he turns away and becomes arrogant, far away from the Right Path. And when evil touches him he is in great despair. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
