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 When the affliction decreed by Us befell them, they did not humble themselves, but rather their hearts hardened, for Satan had made all their doings seem fair to them. 43 When they had become oblivious of what they were warned, We opened wide the gates of everything to them; yet as they rejoiced at what they were given, We caught them unawares, and they were filled with despair. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 Say (O Muhammad!): What do you think? If Allah should take away your hearing and your sight and seal your hearts - who is the god, other than Allah, who could restore them to you? Behold, how We put forth Our signs in diverse forms, and yet they turn away from them. 46 Say: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust people? 47 We do not send Messengers except as bearers of glad tidings and warners. So, he who believes in their message and mends his conduct need have no fear and need not 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 (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
