From Horses to the Unseen: The Expansive Meaning of Qur’an 16:8
﴿And [He created] horses, mules, and donkeys for you to ride and as adornment. And He creates that which you do not know.﴾ (Qur’an 16:8) Regarding His saying: ﴿And He creates that which you do not know﴾ — this refers to things that would come into existence after the revelation of the Qur’an: things which people would ride on land, sea, and air, and which they would use for their benefits and interests. He did not mention them specifically by name, because Allah Most High mentions in His Book only what His servants already know, or what they know something similar to. As for that which has no known counterpart, if it were mentioned explicitly, they would not recognize it nor understand what was intended. Therefore, He mentions a comprehensive, general expression that includes what they know and what they do not know. This is similar to how the bliss of Paradise is described: He mentions from it what we know and can observe a likeness of — such as date-palms, grapes, and pomegranates — while leaving unspecified, in a general manner, that for which we have no known equivalent.
