An-Nahl 16:114

Fakuloo mimma razaqakumu Allahuhalalan tayyiban washkuroo niAAmataAllahi in kuntum iyyahu taAAbudoon

Then eat of what Allāh has provided for you [which is] lawful and good. And be grateful for the favor of Allāh, if it is [indeed] Him that you worship.

So, eat the permissible and pure things from what Allah has provided you, and be grateful for the bounty of Allah, if you worship Him alone.
