BE CONSTANT in [thy] prayer from the time when the sun has passed its zenith till the darkness of night, and [be ever mindful of its] recitation at dawn: for, behold, the recitation [of prayer] at dawn is indeed witnessed [by all that is holy]. 78 And during a part of the night, pray Tahajjud beyond what is incumbent on you; maybe your Lord will raise you to a position of great glory. 79 And pray: "My Lord! Cause me to enter wherever it be, with Truth, and cause me to exit, wherever it be, with Truth, and support me with authority from Yourself." 80 And say: 'The truth has come, and falsehood has vanished away; surely falsehood is ever certain to vanish.' 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
