Keep the prayer established, from the declining of the sun until darkness of the night, and the Qur’an at dawn; indeed the angels witness the reading of the Qur’an at dawn. 78 And during the night wake up and pray, as an additional prayer: it may well be that your Lord will raise you to a station of praise and glory." 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 has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." 81 And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust. 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
