question #3 Sahih al-Bukhari 7322, Book 96, Hadith 52 : What lessons can be learned from the Prophet’s (ﷺ) response to the bedouin’s request to cancel his pledge?

A bedouin gave the Pledge of allegiance for embracing Islam to Allah’s Messenger (ﷺ), and then he got an attack of fever in Medina and came to Allah’s Messenger (ﷺ): and said, “O Allah’s Messenger (ﷺ)! Cancel my pledge.” Allah’s Messenger (ﷺ) refused to do so. The bedouin came to him again and said, “Cancel my pledge,” but he refused again, and then again, the bedouin came to him and said, “Cancel my pledge,” and Allah’s Messenger (ﷺ) refused. The bedouin finally went away, and Allah’s Messenger (ﷺ) said, “Medina is like a pair of bellows (furnace), it expels its impurities while it brightens and clears its good.’
