Establish regular prayers - at the sun's decline till the darkness of the night, and the morning prayer and reading: for the prayer and reading in the morning carry their testimony. 78 And as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 79 And say: My Lord! make me to enter a goodly entering, and cause me to go forth a goodly going forth, and grant me from near Thee power to assist (me). 80 And say: 'The truth has come, and falsehood has vanished away; surely falsehood is ever certain to vanish.' 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 bestow a favour upon a person, he turns his back and draws aside; and when evil afflicts him he gives himself up to despair. 83 Say: "Everyone acts according to his own disposition: But your Lord knows best who it is that is best guided on the Way." 84
