We have sent already unto peoples that were before thee, and We visited them with tribulation and adversity, in order that they might grow humble. 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 warning) with which they had been reminded, We opened to them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them to punishment, and lo! They were plunged into destruction with deep regrets and sorrows. 44 So the people that committed wrong were eliminated. And praise to Allah, Lord of the worlds. 45 Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still 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 send the messengers only to give good news and to warn: so those who believe and mend (their lives),- upon them shall be 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 Say: "I tell you not that with me are the treasures of Allah, nor do I know what is hidden, nor do I tell you I am an angel. I but follow what is revealed to me." Say: "can the blind be held equal to the seeing?" Will ye then consider not? 50
