Nor did he say, “The Quran merely mentions istiwāʾ,” or, “Allah has reported istiwāʾ.” Rather, he declared, “Istiwaʾ is known.” In other words, he affirmed that the single term itself is understood; he did not speak of the entire clause.
He also said, “and its ‘how’ is unknown.” Had he meant otherwise, he would have said, “The meaning of istiwāʾ is unknown,” or, “The explanation of istiwāʾ is unknown,” or, “The clarification of istiwāʾ is not known.” What he denied, therefore, was knowledge of the modality of istiwāʾ, not knowledge of istiwāʾ itself.

They do not deny the meaning of istiwāʾ, nor do they regard it as one of the ambiguous texts whose meaning is wholly inaccessible. The early generations were unanimous in explaining it in the very sense upheld by Ahl al-Sunnah.
Some of them said, “He rose over the Throne,” or, “He ascended over the Throne,” while others used similar expressions. These reports from the salaf are firmly established; al-Bukhārī recorded some of them in his Ṣaḥīḥ at the end of the book “Refutation of the Jahmiyyah.”
As for distorted interpretations such as “He took possession” and the like, they are among the innovative exegeses that arose only after the emergence of the Jahmiyyah. It has also been confirmed that following
