Does affirming God's attributes necessitate believing in His corporeality, and if so, is there no harm in asserting it?

"Words for which there is no negation or affirmation in the Quran and Sunnah should not be attributed to Allah, the Exalted, as mere words. Rather, the speaker should be asked to clarify their meaning. If they intend a sound meaning, then the meaning is accepted, not the word itself.

The negation of corporeality (jismīyyah) and anthropomorphism (tajsīm) has not been mentioned in the Quran, Sunnah, or the words of the Salaf. The Salaf neither negated nor affirmed corporeality because the word 'jism' (body) can hold both truth and falsehood. The word 'tajsīm' (anthropomorphism) was not found in the words of the Salaf, neither in negation nor affirmation. The first to invent its condemnation were the Mu'tazilah, who made it a pejorative term for those who affirmed the attributes of Allah.

The statement regarding 'jism' (body), whether in negation or affirmation, is among the innovations of the mutakallimūn (theologians). As for the negation of similitude (tamthīl) and resemblance (tashbīh), it is indicated by the Quran, Sunnah, and the consensus of the Salaf.

The ruling of deeming someone a disbeliever if they believe Allah is a 'jism' applies specifically to those who liken Allah, the Exalted, to His creation.

The book Daf' Shubah al-Tashbīh bi Akuff al-Tanzīh (Repelling the Doubts of Anthropomorphism with the Hands of Transcendence) contains a mixture of the methodology of the Salaf and false statements erroneously attributed to the Salaf."
