[Pooya/Ali Commentary 15:2] Every time when a fresh torment afflicts the disbelievers in the hereafter, they will wish that they had been Muslims. Allah asks the Holy Prophet to leave the disbelievers alone to satisfy their lust for worldly enjoyments without grieving much over their condition (as "the mercy unto the worlds" the Holy Prophet was often worried about the well-being of the people in this world as well as in the hereafter). Although the respite appears pleasant and intoxicating but a dreadful severe chastisement is awaiting them. They were sunk deep in infidelity and wickedness. They would never see the light of true guidance. Imam Ali said: "It breaks my heart when I see your lust for riches and your unbridled covetousness to enjoy the pleasures of this world." The Holy Prophet said: "When perfection is attained by a man he remembers death and all his desires recede to the background; and when misfortune afflicts him all his desires come to the front and (the thought of) death disappears from his mind."
