And when their saying arises from the nature of man to remain in the current state and to be blind to the illumination by the light of reason regarding what removes it in the end, this is clarified so that it is known that his nature contradicts what the purpose of the surah contains of the precision which is the fruit of knowledge. With this knowledge, the extent of His grace upon the one who preserves it according to what He has created him upon of the best form is known. He confirms by saying that everyone denies that his nature could be like that: "And if We were to let the human taste..." meaning: by what We have of greatness, "the human" meaning: this type that is self-aware; and since one of the ugliest traits is the possession of what is borrowed. And the blessings are loans from Allah, He grants them to whom He wills from His servants. He presented the connection as a proof of the loan and said: "From Us, a mercy" meaning: a blessing as a favor from Us upon him, not by his own strength or power, from a direction he does not hope for, as indicated by the tool of doubt. And We enabled him to enjoy it as the taster is enabled by the tasted. "Then We took it away" meaning: by what We have of greatness, even if he dislikes that "from him" as a taking of our right. "Indeed, he is despairing" meaning: extremely hopeless that he will return to him like it. "Ungrateful" meaning: greatly concealing what has been given to him of honor, for that is his nature and his character, except for whom your Lord has mercy.
