Is it true that Shaykh al-Islam Ibn Taymiyyah was the first to say that the terms "al-jism" (body), "al-badan" (physical body), and "al-jasad" (corporeal body) are ambiguous – neither to be accepted nor rejected – and that no one before him had made this statement, and that the early scholars (Salaf) completely rejected these terms and condemned whoever uttered them?

Regarding ambiguous terms that bear more than one meaning and for which there is no definitive text, such as "direction" (al-jiha) and "space" (al-ḥayyiz): if a valid meaning is intended, it is accepted; but if a false meaning is intended, it is rejected.

Whatever indicates imperfection is negated from Allah the Almighty, due to His absolute perfection.

The terms "flesh" (al-jasad) and "body" (al-badan) are negated from Allah the Almighty, because they denote flesh and blood, and this is an anthropomorphism.

As for the term "corporeality" (al-jism), it requires clarification: its linguistic meaning (flesh and body) is negated from Allah; and the meaning of composition from parts or from matter and form is also negated. As for the third meaning: "an existent being subsisting by itself," this is true, but using the term "corporeality" for it is an innovation.
