Intellectually Impossible vs. Intellectually Beyond Us

Imām Ibn Taimiyyah, may Allāh have mercy on him, said:

A distinction must be made between that which the intellect knows is invalid and impossible [on the one hand] and that which the intellect is unable to conceive of [or] gain knowledge of [on the other].

The former is [from the realm of] things that are intellectually impossible; the latter, from the things that are intellectually beyond [us]. And the Messengers [of Allah] tell us of the latter.
