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 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 come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 Say: 'Truth has come and falsehood has vanished. Indeed, falsehood will certainly vanish' 81 And We reveal by means of the Qur'an that which is a healing and a mercy unto the believers, and it only increaseth the wrong-doers in loss. 82 When We do favors to the human being, he disregards it and turns away from it. When evil afflicts him, he becomes despairing. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
