Sahih Muslim Chapter 6 #1980:
Abu Hurairah (ra) narrated that the Messenger of Allah (saw) said: "Jannah and the Fire (Hell) argued, and the Fire (Hell) said, 'I have been given the privilege of receiving the arrogants and the tyrants.' Jannah said. 'What is the matter with me? Why only the weak and the humble enter me?' On that, Allah said to Jannah, 'You are My Mercy which I bestow on whoever I wish to My slaves.' Then Allah said to the (Hell) Fire, 'You are My punishment by which I punish whoever I wish of My slaves. And each of you will have its fill.' As for Fire (Hell), it will not be filled untill Allah places His Foot on it whereupon it will say, 'Enough, enough.' At that point it will be filled, and its sides will contract; and Allah will not wrong any of his creatures. As regards Jannah, Allah will create a new creation to fill it with"
Doesn't this contradict to the fact that Allah does not have a physical appearance like that of his creatures? Or is it something we cannot understand and the word "Foot" is used instead because our brain is incapable of understand what Allah truly is.
