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 When the suffering reached them from us, why then did they not learn humility? On the contrary their hearts became hardened, and Satan made their (sinful) acts seem alluring to them. 43 When they forgot (all) the advice that they had received, We granted them all means of happiness but they were left in despair when We suddenly took Our bounties back from them. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away. 46 Tell them, "Have you considered that if God's torment was to befall you suddenly or in public, would anyone else be destroyed except the unjust?" 47 And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come 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 (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
