Mohammed - Description given by Abdu'l Baha of the Messenger of God 

Remaster of a description of Mohammed by Abdu'l-Baha read by Paul Pearman (Some Answered Questions)
Islam has a negative perspective from people and these words are a relish most ears need to hear to dispel the bitterness people hold towards Islam.
Islam attained a very high spiritual state, but western scholars are prone to judging it by Christian standards. One cannot call one world Faith superior to another, as they all come from God; they are progressive, each suited to certain needs of the times.
Shoghi Effendi, Lights of Guidance, p. 494-495
Muhammadanism is not only the last of the world religions, but are fuller Revelation than any one preceding it. The Qur'án is not only more authoritative than any previous religious gospel, but it contains also much more ordinances, teachings and precepts, which taken together constitute a fuller Revelation of God's purpose and law to mankind than Christianity, Judaism or any other previous Dispensation. This view is in complete accord with the Bahá’í philosophy of progressive revelation, and should be thoroughly accepted and taught by every loyal Christian Bahá’í.
