Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is 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: The truth has come and the falsehood has vanished; surely falsehood is a vanishing (thing). 81 And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
