Say your prayers from the decline of the sun, until nightfall; and at dawn -- the recitation at dawn is indeed 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 (O Muhammad SAW): My Lord! Let my entry (to the city of Al-Madinah) be good, and likewise my exit (from the city of Makkah) be good. And grant me from You an authority to help me (or a firm sign or a proof). 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 And We send down, of the Koran, that which is a healing and a mercy to the believers; and the unbelievers it increases not, except 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, (O Prophet): "Each one acts according to his own manner. Your Lord knows well who is best-guided to the Right Path." 84
