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 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 So when they forgot the advices made to them, We opened the gates of all things for them; to the extent that when they were rejoicing for what they had received, We seized them suddenly, hence they remained dejected. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 Say, "If God should take away your hearing and your sight and seal your hearts, who is the deity who could restore it to you save God?" See how We explain the signs to them in diverse ways, yet they turn away. 46 Ask them, "Tell me, if the punishment of God came upon you suddenly or predictably, would any but the wrongdoers be destroyed?" 47 And We send [Our] message-bearers only as heralds of glad tidings and as warners: hence, all who believe and live righteously - no fear need they have, and neither 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
