Quran 17.81-83
And say: Truth hath come and falsehood hath vanished away. Lo! falsehood is ever bound to vanish. And We reveal of the Qur'an that which is a healing and a mercy for believers though it increase the evil-doers in naught save ruin. And when We make life pleasant unto man, he turneth away and is averse; and when ill toucheth him he is in despair.
