Establish the prayer at the decline of the sun till the darkening of the night and the Koran recital at dawn. Surely, the Koran recital at dawn is witnessed. 78 And of the night - keep the vigil therein, as an act of supererogation for thee; belike thy Lord will raise thee up in a station praised. 79 And say: 'My Lord, lead me in with a just ingoing, and lead me out with a just outgoing; grant me authority from Thee, to help me.' 80 Say, "Truth has come and falsehood has disappeared. Falsehood is always 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 bless man, he turns away, and withdraws aside; but when evil visits him, he is in 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
