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 Then why did they not submit when Our punishment came upon them? But their hearts were hardened, and Satan made things they were doing look attractive 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 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, "Have you considered: if Allah should take away your hearing and your sight and set a seal upon your hearts, which deity other than Allah could bring them [back] to you?" Look how we diversify the verses; then they [still] turn away. 46 Say: 'What think you? If God's chastisement comes upon you, suddenly or openly, shall any be destroyed, except the people of the evildoers?' 47 We send forth Our Messengers only to give glad tidings to mankind and to warn them. Those who believe and mend their ways shall have nothing to fear or to be saddened. 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, [O Muhammad], "I do not tell you that I have the depositories [containing the provision] of Allah or that I know the unseen, nor do I tell you that I am an angel. I only follow what is revealed to me." Say, "Is the blind equivalent to the seeing? Then will you not give thought?" 50
