We had sent (Our guidance) to the nations who lived before you and afflicted them with distress and adversity so that they might submit themselves (to God). 42 if only, when Our might came upon them, they had been humble! But their hearts were hard, and Satan decked out fair to them what they were doing. 43 Then when they forgot that whereof they were reminded We opened upon them the doors of everything, until when they boasted of that which they were given, We laid hold of them on a sudden, and lo! they were dumbfounded. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 (Muhammad), ask them, "Have you ever considered that if God was to disable your hearing and vision and veil your hearts, could anyone besides Him restore them?" Look at how plainly We show them the evidence (of the Truth) but they always ignore it. 46 Say, “What is your opinion – if the punishment of Allah were to come upon you suddenly or openly (with forewarning), who would be destroyed except the disbelieving people?” 47 We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them 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 Say, "I do not say to you that I possess the treasures of God, nor do I know the unseen, nor do I say to you that I am an angel. I follow only that which is revealed to me." Say, "Are the blind and the seeing alike? Can you not then think?" 50
