Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is witnessed. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy station. 79 Say: 'Lord, grant me an entrance of sincerity and an exit of sincerity, and give me from Yours a victorious power' 80 And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." 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 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 to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
