What is the meaning of the hadith (that Allah places His foot in the Fire . .) and that Allah mixes with His creation?

The student : Regarding the hadith of the Mighty One when He places His foot in the Fire, the Asha'irah interpret this hadith with two doubts. The first doubt is: that Allah would be mixed with His creation, which is the Fire. The second thing

The Shaykh : Excuse me, what is the first thing?

The questioner : That Allah would be mixed in the Fire, mixed with His creation. And the other doubt is that the people of the Fire see Him; so how do we respond to this?

The Shaykh : . And what is the first doubt that is raised against some of the divine attributes? This comes from asking how Allah (Mighty and Majestic) is and likening Him to His creation, just as they denied the descent, and likewise they deny this placement. The principle regarding the divine attributes, as with the principle in all matters of the unseen, is that it is not permissible to expand upon them, nor is it permissible to analogize the unseen to the seen. And Allah (Mighty and Majestic), as He said, . So we believe in what came in the Book and the Sunnah without asking how, without likening, and also without denial or negation through figurative interpretation or the like. And as Ibn al-Qayyim (may Allah have mercy on him) said:
"Knowledge is: Allah said, His Messenger said, the Companions said; it is not deception.
Knowledge is not setting you up for foolish disagreement between the Messenger and the opinion of a jurist.
Nor is it denying the attributes and their negation out of fear of denial of the divine attributes or likening Allah to creation."
So we believe in everything that came with the addition of "There is nothing like Him." So if the believer believes in this, he is saved from the two corruptions: the corruption of likening Allah to creation and the corruption of denial of the divine attributes. Yes, others.
