Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 Yet why did they not, when Our punishment came to them, humble themselves? But their hearts hardened and the Shaitan made what they did fair-seeming to them. 43 When they had become oblivious of what they were warned, We opened wide the gates of everything to them; yet as they rejoiced at what they were given, We caught them unawares, and they were filled with despair. 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 Say thou look ye now, were Allah's torment to come upon you on a sudden or openly, would there be destroyed any but the wrong-doers? 47 We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them neither shall they grieve. 48 But those who belie Our verses, punishment shall touch them for their misdeeds. 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
