Verily, We sent (Messengers) to many nations before you (O Muhammad SAW). And We seized them with extreme poverty (or loss in wealth) and loss in health with calamities so that they might believe with humility. 42 But when misfortune befell them from Us why did they not humble themselves? Their hearts had hardened and Satan had made their deeds seem fair to them. 43 So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair. 44 So the roots of the people who were unjust were cut off; and all praise is due to Allah, the Lord of the worlds. 45 Say: 'What would you see if Allah took away your hearing and your sight, and set a seal upon your hearts, who is a god, other than Allah, to bring it back to you' Look how We make plain to them Our verses, and yet they turn away. 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 And We did not send Noble Messengers except as Heralds of glad tidings and warnings; so upon those who accept faith and reform themselves, shall be no fear nor shall they grieve. 48 But those who reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 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
