Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever witnessed. 78 Say a supererogatory prayer at the hour of the first watch: Your Lord may raise you to a most exalted 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: "The truth has now come [to light,] and falsehood has withered away: for, behold, all falsehood is bound to wither away!" 81 What We are sending down in the course of revealing the Qur'an is a healing and a grace for those who have faith; but it adds only to the ruin of the wrong-doers. 82 And when We show favour unto man, he turneth away and withdraweth on his side; and when evil toucheth him he is ever despairing. 83 Say: 'Every man works according to his own manner; but your Lord knows very well what man is best guided as to the way.' 84
