And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 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 But when they forgot the warning they had received, We opened to them the gates of all (good) things, until, in the midst of their enjoyment of Our gifts, on a sudden, We called them to account, when lo! they were plunged in despair! 44 So the people that committed wrong were eliminated. And praise to Allah, Lord of the worlds. 45 Say, “What is your opinion – if Allah were to take away your hearing and your sight and seal your hearts, then is there a God besides Allah who could restore it for you?” Observe how We explain the verses to them, yet they turn away! 46 Say: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 And We send not apostles but as announcers of good news and givers of warning, then whoever believes and acts aright, they shall have 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 Say: 'I do not say to you, "I possess the treasuries of God"; I know not the Unseen. And I say not to you, "I am an angel"; I only follow what is revealed to me. Say: 'Are the blind and the seeing man equal? Will you not reflect?' 50
