BE CONSTANT in [thy] prayer from the time when the sun has passed its zenith till the darkness of night, and [be ever mindful of its] recitation at dawn: for, behold, the recitation [of prayer] at dawn is indeed witnessed [by all that is holy]. 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 And when We bestow Our Grace on man (the disbeliever), he turns away and becomes arrogant, far away from the Right Path. And when evil touches him he is in great despair. 83 Say thou: everyone worketh after his disposition, and your Lord is the Best Knower of him who is best guided on the way. 84
