Keep up prayer from the declining of the sun till the darkness of the night and the morning recitation; surely the morning recitation 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 proclaim: "The Truth has come, and falsehood has vanished. Surely falsehood is ever bound to vanish." 81 And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers 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: "Everyone acts according to his own disposition: But your Lord knows best who it is that is best guided on the Way." 84
