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 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 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 and [in the end,] the last remnant of those folk who had been bent on evildoing was wiped out. For all praise is due to God, the Sustainer of all 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: 'What think you? If God's chastisement comes upon you, suddenly or openly, shall any be destroyed, except the people of the evildoers?' 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 Tell them: "I do not say that I possess the treasures of God, or have knowledge of the Unknown, or that I am an angel. I only follow what is sent down to me." And say: "How can a blind man and a man who can see, be alike? Will you not reflect?" 50
