And Allâh is not going to leave (you), the believers, as you are, unless He has distinguished the corrupt from the good. Nor is Allâh going to reveal fully to (everyone of) you, the unseen; but Allâh chooses (for His Messages) such of His Messengers as He will. Believe, therefore in Allâh and His Messengers; and (remember) if you believe (truly) and guard against evil then there is for you a great reward.
