The Companions of the Prophet, God bless Him and grant Him peace, were almost all converts, and not all of them were Arab. Salman was Aryan (now called Iranian), Bilal was Black, and Suhaib was an Arab raised among the Byzantines. Our Prophet (sallAllahu alayHi wasallam) also dressed in a variety of styles; He wore Ethiopian shirts, Yemeni cloaks, Arabian lungis, and Byzantine garments. The Prophet (sallAllahu alayHi wasallam) was already practicing global culture in the seventh century, knowing that His religion would be embraced by many cultures, just as He predicted.
