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 a supererogatory prayer at the hour of the first watch: Your Lord may raise you to a most exalted station. 79 And say [in thy prayer]: "O my Sustainer! Cause me to enter [upon whatever I may do] in a manner true and sincere, and cause me to leave [it] in a manner true and sincere, and grant me, out of Thy grace, sustaining strength!" 80 And say: 'The truth has come, and falsehood has vanished away; surely falsehood is ever certain to vanish.' 81 And We send down from the Quran that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss. 82 And when We show favour unto man, he turneth away and withdraweth on his side; and when evil toucheth him he is ever 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
