Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 If only they humbled themselves when Our scourge overtook them! But their hearts were hardened, and satan decorated to them what they were doing. 43 So when they forgot the advices made to them, We opened the gates of all things for them; to the extent that when they were rejoicing for what they had received, We seized them suddenly, hence they remained dejected. 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher of the worlds. 45 Say: "Think ye, if Allah took away your hearing and your sight, and sealed up your hearts, who - a god other than Allah - could restore them to you?" See how We explain the signs by various (symbols); yet they turn aside. 46 Ask them, "Tell me, if the punishment of God came upon you suddenly or predictably, would any but the wrongdoers be destroyed?" 47 We do not send apostles but to give good tidings and to warn. Then those who believe or reform will have neither fear nor regret. 48 But as for those who deny Our revelations, torment will afflict them for that they used to disobey. 49 (Muhammad), tell them, "I do not claim to have all the treasures of God in my hands, nor to know the unseen, nor do I claim to be an angel. I follow only what is revealed to me (from God)." Say to them, "Are the blind and the seeing equal?" Why then do you not think? 50
