|Very interesting, creative. The he/she pronoun gets very tiresome. If you want to make it clear a character is genderless just specify that at the beginning and use "he", which is an accepted grammatical convention. Or pick a gender, I'm sure people will be able to suspend disbelief.
"They were in a Divine Room, of course, since no universe existed at this time, and therefore it is not like any room that you can imagine. However, within this Divine Room, Khaliq had a number of things that he/she found comforting and fun."
Something about this paragraph bugs me, and I'm really not sure what it is. It's just worded awkwardly. Try this:
"They were in a Divine Room, different from any room that a human being could ever conceive. Inside the room Khaliq kept several pets for comfort."
Or you can even remove the room entirely and try this:
"Iblis looked around for inspiration and spotted Khaliq's beloved pets, a wolf, cat, fly, etc..."
Also, this sentence:
"...Did you have any suggestions?"
...Should be "DO you have any suggestions?", not did. Present tense.
Just in general cut down on unnecessary words. You're very wordy and instead of making the story feel more "epic", which I think is what you're going for, it just looks "stretched", like you're stuffing in words for the heck of it. It strangles your voice and looks awkward.
Otherwise, very good. I like the image of what are in my head Egyptian gods playing cards. I also like how you incorporated modern physics into a creation myth while managing to retain a mythical feeling. It's my type of story.
