“Muslims believe that Muhammad received revelations from God.  Muhammad said this was the same God that had spoken to Abraham, Jesus and prophets and religious figures of Judaism and Christianity.”  p453 My World History (Early Ages)

In the above text the word revelations is underlined. Why the underline? Who put that in? No other words in this section are underlined. This is a blatant “in your face” to all Christians and Jews who do not believe that to be true. Revelation 21:18 disproves the above.
