'The Establishment of the Sacred') is an Islamic theological book, written by the Shafi'i-Ash'ari scholar Fakhr al-Din al-Razi (d. 606/1209), as a methodical refutation of the Karramiyya and other anthropomorphists.
[1][2] Fakhr al-Din al-Razi wrote this work to counter the book Kitab al-Tawhid composed by the ultra-traditionalist Ibn Khuzayma (d. 311/923).
That is, in fact, his definition of anthropomorphism: al-Razi maintains that the one God is not present in a direction; He is not a space-occupying entity and is not a body, an assertion for which he provides proofs based on rational and textual evidence.
The claims he contradicts are namely those held by the corporealist Karramites and the ultra-traditionalists who affirmed God's direction (jiha) and its veridical meaning (as haqiqa: truth, reality).
In his discussion al-Razi articulates the Ash'ari stance on this matter and explains the proper figurative interpretation (ta'wil), according to his opinion.
