Establish regular prayers - at the sun's decline till the darkness of the night, and the morning prayer and reading: for the prayer and reading in the morning carry their testimony. 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 thou: O my Lord! cause me to enter a rightful entrance and cause me to go forth with a rightful outgoing, and appoint for me from before Thee an authority helpful. 80 And say: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 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 for [it often happens that] when We bestow Our blessings upon man, he turns away and arrogantly keeps aloof [from any thought of Us]; and when evil fortune touches him, he abandons all hope. 83 Say (O Muhammad SAW to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions, etc.), and your Lord knows best of him whose path (religion, etc.) is right." 84
