Chapter: The giving of the Baia by the bedouins

A bedouin gave the Pledge of allegiance to Allah's Messenger (ﷺ) for Islam and the bedouin got a fever where upon he said to the Prophet (ﷺ) "Cancel my Pledge." But the Prophet (ﷺ) refused. He came to him (again) saying, "Cancel my Pledge.' But the Prophet (ﷺ) refused. Then (the bedouin) left (Medina). Allah's Apostle said: "Medina is like a pair of bellows (furnace): It expels its impurities and brightens and clears its good."
