I can't promise anything but I'll try to keep the spoilers minor in what's to come.
We start our journey with our Sheikh(who has no first name as far ahead as the mid-end of the movie) in a dream. Basically, a dream that paints us half the picture of our protagonist. He fears death, not only because it's, you know, Death, but because it means that his chance to improve his good-standing with god is gone. And so we start at the depth of our character and continue exploring it outwards.
Later, we get to catch glimpses of his childhood, and adolescence. Both well-acted and well-written. We witness the emotional traumas he goes through during these periods and how they made him what he is today. El-Kedwany plays a master-class part in portraying the child and adolescent Sheikh's father. He joins both abusive and preaching characteristics in a well-developed character.
To steer off giving any major spoilers, of what I think is a movie not just about a story or some events, I will just give a final opinion of what I saw the main character as. He is a very religious man, though not a fanatic. A good man, albeit flawed and haunted. A sad man, an imprisoned man, although with no warden but himself.
