“And We did not send thee (Muhammad) but for the whole mankind”. (Qur’an, 34:28)
Look at the major religions of the world minutely and you will find that it is only Islam which claimed from the beginning to be the religion for the whole mankind.
God sent, before Muhammad, thousands of prophets and apostles to different places and nations to guide their people to the right path. It should be mentioned here that the word ‘Prophet’, when used by a Muslim, does not mean ‘one who foretells the events’. Foretelling the events is not a very important function of a ‘Prophet’. A prophet, according to Islam, is sent by God to call people to His path. He is the link between Allah and His creatures, and by following his foot-prints the followers can be sure of receiving the glory of God.
Anyhow, when as a result of the efforts of those Prophets mankind reached the stage of maturity, the Holy Prophet of Islam was sent by God for the whole mankind. He re-affirmed, revived, consolidated and perfected the teachings of the earlier prophets (which by passage of time had become distorted and disfigured).
Muhammad come in the world, announcing that, “I have been sent to all people-red and black and yellow”. Among his early followers were people from Ethiopia, Iran, Rome and India.
According to the Qur’an, Allah is not a tribal god but the ‘Lord of Universe’; and the Holy Prophet is ‘The Mercy for the universe’.
By sending his messengers to Asia Minor, Iran, Egypt, Ethiopia, Syria, Yemen, Bahrain, Oman and many other places, calling those people to ‘come within the fold of Islam, Muhammad left an undeniable proof that his was the universal religion, unfettered with the shackles of tribe, religion, color or race.
