what happens to uncle Taher? why could he not get the help he needed?(Passport)

They learn that Uncle Taher has had a third heart attack and they rush to the hospital.  The doctors tell Marjane’s aunt that Uncle Taher needs open-heart surgery and that he must go to England for the surgery. Marjane’s aunt goes to the director of the hospital to ask for a passport for her husband to go to England. She is surprised to learn that the director of the hospital is her former window washer. He has been made director of the hospital because of his extreme religious zealotry. The director tells her that “if God wills it,” Taher will receive the passport. She is furious that “the fate of my husband depends on a window washer!”
