Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is witnessed. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy 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: Truth hath come and falsehood hath vanished away. Lo! falsehood is ever bound to vanish. 81 And We send down in the Qur’an that which is a cure for the Muslims, and a mercy – and it increases only ruin for the unjust. 82 And when We bestow favor upon the disbeliever, he turns away and distances himself; and when evil touches him, he is ever despairing. 83 Say: 'Every man works according to his own manner; but your Lord knows very well what man is best guided as to the way.' 84
