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 thou: the truth is come, and falsehood hath vanished; verily falsehood is ever vanishing. 81 And We send down from the Quran that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss. 82 Yet when We bestow Our favours on man, he turns away and becomes remote on his side (instead of coming to Us), and when evil seizes him he gives himself up to despair! 83 Say: Each one doth according to his rule of conduct, and thy Lord is Best Aware of him whose way is right. 84
