Is the saying permissible: "Were they to grant me the world and the Gardens of Bliss, I would not abandon my love for you throughout the years"?

If the speaker intends the Gardens of Delight, then this statement is impermissible, due to its implication of diminishing the reward of Allah and preferring a worldly beloved over it. The world, in the sight of Allah, is not even worth the wing of a mosquito. It also contains an exaggeration in the love of the beloved and suggests a flaw in the speaker's perception, and an emptiness in their heart regarding attachment to Allah and the Hereafter. It should be avoided.
