Surely, the Koran recital at dawn is witnessed. 78 As for the night there is a voluntary deed for you to keep vigil in part it.

Batil is ever bound to vanish." 81 What We have sent down of the Qur'an is a healing and a grace for the faithful, and adds only loss for the sinners. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
