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, when Our disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto them! 43 So, when they forgot what they had been reminded of, We opened the gates of all things so that while they rejoiced in what they had been granted We seized them suddenly and they were plunged into utter 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 do you think? If God should take away your hearing and your sight and seal your hearts - what deity but God is there that could bring it all back to you?" Behold how many facets we give to our messages - and yet they turn away in disdain! 46 Say: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?" 47 We send the messengers only to give good news and to warn: so those who believe and mend (their lives),- upon them shall be no fear, nor shall they grieve. 48 But those who belie Our verses, punishment shall touch them for their misdeeds. 49 Say: 'I do not tell you that I have the treasuries of Allah or know the unseen, nor do I claim to be an angel. I follow only that which is revealed to me' Say: 'Are the blind and the seeing alike? Will you not think' 50
