(541) And nothing prevents men from believing, (now) when the guidance (the Qur'an) has come to them, and from asking Forgiveness of their Lord, except that the ways of the ancients be repeated with them (i.e. their destruction decreed by Allah), or the torment be brought to them face to face?

(542) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, but turns away from them, forgetting what (deeds) his hands have sent forth.

And I did them not of my own accord. That is the interpretation of those (things) over which you could not hold patience."

(549) Say (O Muhammad صلى الله عليه وسلم): "Shall We tell you the greatest losers in respect of (their) deeds?

(550) "Those whose efforts have been wasted in this life while they thought that they were acquiring good by their deeds.
