On reflection, one comes to appreciate that this is a great blessing vouchsafed to mankind through the Arabian Prophet, Muhammad (pbuh). It has been this differentiation between man and man that has , more than anything else, ruined mankind.For him, it did not matter from which class, colour; language or nationality his followers came. Suhayl the Roman would be among his honored companions; Bilal the Abyssinian who could not properly pronounce many an Arabic sounds would have the honor of calling the faithful to the prayer, and Salman the Persian would be referred to as from us the Ahul-ul-Bayt," an honor which no aristocratic Qurayshite Arab would have.
Let us now turn to the rules for human welfare which the Holy Prophet (pbuh) propagated through the teachings of Islam and the seizure of power to enable him not only to guarantee human well-being but to unite all human beings in one Ummah.
