Came across a Hadith on an anti Islamic website. It states that the testimony of the Bedouin desert dwelling Arab was not to be taken over a townsman. This has lead to the claim that Islam is racist and discriminatory towards a particular denomination of the Arab diaspora. At first I merely presumed that it was in unauthentic Hadith as these anti Islamist websites love to use but upon closer inspection. I found that it's actually sahih.

https://sunnah.com/abudawud/25/32Could someone please explain why rasulallah saw instructed this?
