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 If only they humbled themselves when Our scourge overtook them! But their hearts were hardened, and satan decorated to them what they were doing. 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 Then the people who committed wrong were cut off completely. And all praise is unto Allah, the Lord of the worlds. 45 Say: 'What think you? If God seizes your hearing and sight, and sets a seal upon your hearts, who is a god other than God to give it back to you?' Behold how We turn about the signs! Yet thereafter they are turning away. 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 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
