Establish the prayer at the decline of the sun till the darkening of the night and the Koran recital at dawn. Surely, the Koran recital at dawn is witnessed. 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 thou: the truth is come, and falsehood hath vanished; verily falsehood is ever vanishing. 81 We sent down of the Koran that which is a healing and a mercy to believers, but to the harmdoers it does not increase them, except in loss. 82 And when We bestow favor on man, he turns aside and behaves proudly, and when evil afflicts him, he is despairing. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
