Keep up prayer from the declining of the sun till the darkness of the night and the morning recitation; surely the morning recitation is witnessed. 78 And some part of the night awake for it, a largess for thee. It may be that thy Lord will raise thee to a praised estate. 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 We sent down of the Koran that which is a healing and a mercy to believers, but to the harmdoers it does not increase them, except in loss. 82 And when We bless man, he turns away, and withdraws aside; but when evil visits him, he is in despair. 83 Say, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
