Answer: Jews and Christians were allowed to spread their own beliefs.
Explanation:
According to the basic postulates of Islam, no compulsion in religion is allowed. Therefore, early Muslims held on to these beliefs. Prophet Muhammad said on one occasion when asked about Jews and Christians, that is, their ideas that he had nothing against them because they were "the people of the book" (referring to their mention in the Quran). In his book Ethics, the German philosopher Goethe declared to Muhammad that he was the most tolerant religious figure or leader in history. The holy book of Muslims explicitly states "There is no compulsion in religion", and in keeping with this statement, a positive effect in the early spread of Islam occurred. Namely, after many peoples realized the degree of tolerance among Muslims, they converted to Islam. This was one of the main factors in the rapid spread of early Islam in the Arabian Peninsula.
