We had sent (Our guidance) to the nations who lived before you and afflicted them with distress and adversity so that they might submit themselves (to God). 42 So why did they not humbly plead when Our punishment came to them? But their hearts were hardened and the devil made all their deeds appear good to them! 43 Then, when they forgot that whereof they had been reminded, We opened unto them the gates of all things till, even as they were rejoicing in that which they were given, We seized them unawares, and lo! they were dumbfounded. 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher 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, "Have you considered: if the punishment of Allah should come to you unexpectedly or manifestly, will any be destroyed but the wrongdoing 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 reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), the torment will touch them for their disbelief (and for their belying the Message of Muhammad SAW). [Tafsir Al-Qurtubi]. 49 Tell them: "I do not say that I possess the treasures of God, or have knowledge of the Unknown, or that I am an angel. I only follow what is sent down to me." And say: "How can a blind man and a man who can see, be alike? Will you not reflect?" 50
