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 Say your special (tahajjud) prayer during some part of the night as an additional (obligatory) prayer for you alone so that perhaps your Lord will raise you to a highly praiseworthy position. 79 And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." 80 Say, "Truth has come and falsehood has disappeared. Falsehood is always bound to wither away." 81 THUS, step by step, We bestow from on high through this Qur'an all that gives health [to the spirit] and is a grace unto those who believe [in Us,] the while it only adds to the ruin of evildoers: 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
