Say your prayer when the sun declines until the darkness of night and also at dawn. Dawn is certainly witnessed (by the angels of the night and day). 78 And from [part of] the night, pray with it as additional [worship] for you; it is expected that your Lord will resurrect you to a praised station. 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 And We send down in the Qur’an that which is a cure for the Muslims, and a mercy – and it increases only ruin for the unjust. 82 When We bestow a favour upon a person, he turns his back and draws aside; and when evil afflicts him he gives himself up to despair. 83 Say (O Muhammad SAW to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions, etc.), and your Lord knows best of him whose path (religion, etc.) is right." 84
