Its author said in the introduction, "It is a known fact that every language has one or more terms that are used in reference to God and sometimes to lesser deities. This is not the case with Allah. Allah is the personal name of the One true God. Nothing else can be called Allah. The term has no plural or gender. This shows its uniqueness when compared with the word "god," which can be made plural, as in "gods," or made feminine, as in "goddess." It is interesting to notice that Allah is the personal name of God in Aramaic, the language of Jesus and a sister language of Arabic."

I will raise them up a prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
