There are many events and Quranic verses that talk about the characteristics of the Bedouins, and this is due to their ignorance and that they are arrogant and love wars and killing.
1-Narrated Jabir bin 'Abdullah As-Salami: 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.'
