Make a comparison between Khosrove and Mourad.

Although Khosrove and Mourad differ in age, they share a number of common characteristics. Firstly, they are both considered crazy by other members of their family. Khosrove is considered crazy because of his "temper" and impatience, while Mourad has a rebellious spirit, shown by his theft of the horse.
Secondly, both Khosrove and Mourad take a relaxed attitude to life. When Khosrove's house caught fire, for instance, he said, "Enough. It is no harm."
Mourad shares a similarly relaxed attitude to life. He sees no problem in stealing the horse, for example, because he fully intends to return it. Just like the fire in Khosrove's house, his theft of the horse is of little consequence.
One area of difference between Khosrove and Mourad lies in their relationships with animals. While Khosrove appears to take no interest in the natural world, Mourad has a deep affinity for animals. He spends his time riding the horse or nursing a sick robin, and he describes himself as having a "way with dogs." In contrast, Khosrove spends his time smoking and drinking coffee, activities that lack any connection to the natural world.

In William Saroyan's short story "The Summer of the Beautiful White Horse," Mourad is the narrator's cousin. Khosrove is Mourad's uncle. According to the narrator, Aram, Mourad was considered the natural descendant of Khosrove, meaning that they share DNA. But in many ways, it is easier to find differences between Khosrove and Mourad because they do not have many things in common. 
Aram says that his cousin Mourad loved life more than anyone he knew. Khosrove is described as irritable and domineering, with his famous phrase, "It is no harm! Pay no attention to it!"
One thing they have in common is that they are both considered crazy. Aram says, "Every family has a crazy streak in it somewhere, and my cousin Mourad was considered the natural descendant of the crazy streak in our tribe. Before him was our uncle Khosrove." Aram also begins the story by describing how everyone thought his cousin Mourad was crazy except for him.
Another thing that Mourad and Khosrove have in common is their reputation. The legacy of the Garoghlanian family is that they are very honest. This is a bit ironic, however, considering Mourad has stolen a horse.
Being members of the Garoghlanian family, they are both poor. The narrator says this:

We were poor. We had no money. Our whole tribe was poverty-stricken. Every branch of the Garoghlanian family was living in the most amazing and comical poverty in the world.
