4.Among the descriptions of the people to whom the Prophet Muhammad (pbuh) was sent, as in the words of the Torah, "They have moved me to jealousy with that which is not God; they have provoked me to anger with their vanities: and I will move them to jealousy with those which are not a people; I will provoke them to anger with a foolish (ignorant) nation." [Deuteronomy 23: 21]
Without a doubt, this description is definitely of the people of the Prophet Muhammad (pbuh), for they were not a nation; rather, they were disparate, warring tribes, without king, ruler, or chief. Additionally, they were ignorant of reading and writing, except for a few.
With the coming of the Prophet Muhammad (pbuh), however, they became brothers who loved each other and supported one another. They came to have a great nation—the Islamic nation—whose leader was the Prophet Muhammad (pbuh). The two greatest empires of the day, Persia and Rome, were subjugated to it, and it became advanced in many different fields of knowledge for its time, while still adhering to the guidance of their prophet, Muhammad (pbuh) and what he urged them to do.
Some of the scholars of the Jews attempted, falsely, maliciously, and spitefully, to attribute this unlearnedness to the Greek civilization, but they failed in doing so, because the Greeks, hundreds of years before the appearance of Jesus (pbuh), were advanced in science and art and they stayed with the rules of the Torah and the other books of the Old Testament, as they claim.
