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 rise from thy sleep and pray during part of the night [as well,] as a free offering from thee, and thy Sustainer may well raise thee to a glorious station [in the life to come]. 79 And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 We reveal the Quran which is a cure and mercy for the believers but does nothing for the unjust except to lead them to perdition. 82 And when We bestow favor on man, he turns aside and behaves proudly, and when evil afflicts him, he is 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
