Establish thou the prayer from the declination of the sun to the darkening of the night, and the recitation at the dawn; verily the recitation at the dawn is ever borne witness to. 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 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 And say: "The truth has now come [to light,] and falsehood has withered away: for, behold, all falsehood is bound to wither away!" 81 And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
