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 But when misfortune befell them from Us why did they not humble themselves? Their hearts had hardened and Satan had made their deeds seem fair to them. 43 Then, when they had forgotten all that they had been told to take to heart, We threw open to them the gates of all [good] things until - even as they were rejoicing in what they had been granted - We suddenly took them to task: and lo! they were broken in spirit; 44 The origins of the unjust people were therefore cut off; and all praise is to Allah, Lord Of The Creation. 45 Say: Have you considered that if Allah takes away your hearing and your sight and sets a seal on your hearts, who is the god besides Allah that can bring it to you? See how We repeat the communications, yet they turn away. 46 Say: 'If the chastisement of Allah were to overtake you unawares or openly shall any except the wrong-doing people be destroyed?' 47 We do not send Messengers except as bearers of glad tidings and warners. So, he who believes in their message and mends his conduct need have no fear and need not 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
