And indeed, We sent Our messages unto people before thy time, [O Prophet,] and visited them with misfortune and hardship so that they might humble themselves: 42 yet when the misfortune decreed by Us befell them, they did not humble themselves, but rather their hearts grew hard, for Satan had made all their doings seem goodly to them. 43 Then, when they had forgotten all that they had been told to take to heart, We threw open to them the gates of all [good] things until - even as they were rejoicing in what they had been granted - We suddenly took them to task: and lo! they were broken in spirit; 44 So of the people who did wrong the last remnant was cut off. Praise be to Allah, Lord of the Worlds! 45 Say: "Imagine if God takes away your hearing and sight, and sets a seal on your hearts, what deity other than God will restore them to you?" See how We inflect Our signs: Even then they turn aside. 46 Say: Can ye see yourselves, if the punishment of Allah come upon you unawares or openly? Would any perish save wrongdoing folk? 47 And We send [Our] message-bearers only as heralds of glad tidings and as warners: hence, all who believe and live righteously - no fear need they have, and neither 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 Say, "I do not say to you that I possess the treasures of God, nor do I know the unseen, nor do I say to you that I am an angel. I follow only that which is revealed to me." Say, "Are the blind and the seeing alike? Can you not then think?" 50
