Assalâmu 'Alaykum akhî, It might be that he is among those who believed that he made repentance, it is known in Ibn Taymiyyah's books that he believes Allâh Most High has a place. If Imâm 'Aliy al-Qâri makes takfîr upon one who attributes place to Allâh Most High then it is highly possible that he believed that Ibn Taymiyyah repented. Akhî, whether ithbât or ta'wîl is not important regarding this, the important thing is that he is against attributing direction, place, limit etc. to Allâh Most High. Ibn Taymiyyah attributed place and direction to Allâh Most High. BarakAllâhu fîkum
