The day of the national Prophet was ended: it had served the purpose for which it was meant, and the day of the World Prophet dawned upon humanity in the person of Holy Prophet Muhammad, to lead it on to the grand idea of the oneness of human race.

In speaking of Prophet Muhammad as World-Prophet, the Holy Qur'an says:

    "We have not sent thee but to ALL MEN as a bearer of good news and as a warner." 34:28

The Arabic for ALL MEN in this verse is 'Kafatul-nas', where even al-nas carries the idea of all people, and the addition of Kaffah is meant to emphasize further that not a single nation was excluded from the heavenly ministration of Prophet Muhammad.

One thing is sure that no other Prophet is spoken of, either in the Holy Qur'an or in any other scripture, as having been sent to the whole of humanity, nor is Prophet Muhammad ever spoken of in the Holy Qur'an as having been sent to his people only.

The distinguishing feature of the world-prophet is that Prophet Muhammad bore testimony to the truth of the previous Prophets of the world. You may turn the pages of all the sacred books and search the sacred history of every nation and you will find that there is but one Prophet who verified the scriptures of all religions and bore testimony to the truth of the Prophets of every nation. In fact, no
one could aspire to the dignity of world-prophet who did not treat the whole humanity as one; and Prophet Muhammad is the only one who did so by declaring that Prophets of God had appeared in every nation and that every one who believed in him must also believe in all the Prophets of the world.

The grand idea of unifying the whole human race and gathering it together under one banner was thus brought to perfection by the World-Prophet. All geographical limitations were swept away as were all bars of colors and race, and the basis of the unity of the human race was laid upon the grand principle that all men, wherever they may be found, were a single nation.
