They're all related. I know there were prophets for every people but those were particularly Ibrahim (as)'s sons and grandsons.The Arabs are treating us like shit and then they expect us to fight with al mahdi with them I know he is the prophets family but come on why does every important person have to be Arab or semetic littlerly no one else if Islam was the religion for everyone Allah would tell every nation their prophets like he told arabia about their ancestor Abraham and his whole family tree don't say it wasn't necessary to say every nations prophet in the Quran they talk about yaqub yunus Yusuf Ismaili ishaq Ibrahim isa but no time for non Arab prophets
