They expelled him from the country, and when the infected part arrived, they built him a hut called by them Al-Karaba, and left with him those who would serve him, who had been sick with smallpox. And if another fell ill, they moved him there, and so on. And this is quarantine itself. A warning to the people of Sudan from smallpox, the Arabs of their desert, because smallpox if it enters their settlements, it annihilates them. That is why you see them, out of fear of the people from it. And a man from the elders of the Bargad, named Uthman wad Alwana, told me that he was sick with smallpox and suffered what he suffered, then God healed him. When his smallpox sores began to heal, flies would swarm him, so he would stand for that reason. He said: One day, as I was sitting, I happened to be at my door when I saw an Arab who came with a gait like a woman. When he saw me, he approached my water jug and greeted me. Then he said, "I adjure you, is this smallpox?" I said, "By God, I lied." He entrusted me with the trust, and I lifted the veil from my face. When he saw me, he let out a great cry and fell to the ground. His Arab brothers came to his aid, and they carried him away. And I, when his brothers came, was afraid lest they kill me. It reached me later that he died three days later. And among the superstitions of the people of Sudan is that they say that smallpox is an animal that is not seen, only its traces. They kill with souls and it kills them. And I heard from many of them that they saw its traces.
