Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 Why did they not submit themselves (to God) when Our torment struck them. Instead, their hearts were hardened and Satan made their evil deeds seem attractive to them. 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 So the roots of the people who did wrong were cut off. And all the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinns, and all that exists). 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, “What is your opinion – if the punishment of Allah were to come upon you suddenly or openly (with forewarning), who would be destroyed except the disbelieving 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 And those who belie Our signs - torment shall touch them for they have been 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
