The Prophet ﷺ said, "He who calls for, fights for, dies for race is not from us.” There is no racism in Islām. Who follows the way of Allāh ﷻ and obeys His ﷻ order is your brother. The Ottoman Empire was an example of this until shayṭān made them racist and they were ruined. Now only Mahdī (as) can end this fitnah.
