What is the scholarly response to one who fabricates against Ibn Taymiyyah his alleged saying regarding the vision of Allah in this world, and discussions concerning the fatwas and visions that occur to a servant while awake?

No one can see Allah with their eyes before death, according to the consensus of the Ahl al-Sunnah wa al-Jama'ah (Sunni Muslims). Whoever claims otherwise is mistaken. However, it is possible to see Allah in a dream in various forms, depending on the faith of the beholder. A dream vision differs from a real vision in wakefulness. Some people in a state of wakefulness might mistakenly believe they have seen Allah with their eyes due to powerful spiritual experiences, but they are wrong in this.
