Answer 1: Means over Message
The military expansion of the Islamic Caliphates in the Middle East, North Africa, and Central Asia was what led to the creation of the merchants and missionaries that arrived in areas not directly conquered by those Caliphates. Then once Islamic beachheads had been established through trade, indigenous Islamic countries would be erected in those areas (East Africa, Indonesia/Malaysia, West Africa, etc.). Within the Islamic Empires, there was incredible pressure to convert to Islam, such as legal inequality between Muslims and Non-Muslims, excessive taxation of Non-Muslims, certain dress requirements for Non-Muslims, etc. resulting in numerous conversions for legal and economic benefits as opposed to honest belief. Of course, we will never know how many people converted because of pressure and how many converted due to the message, but I would be dubious of any claim that held that more converted by message than by means.

Islam !!
The main message of Islam to all peoples is that: "there is only one god. He is the Creator, and therefore only he has the right to be worshipped."
The rise of Islam started with the message that was spread by the Prophet Mohammad. After his death the companions who accompanied him through his journey realized the potential danger in losing the message of Islam and the teachings of the Prophet so they set to jot down the revealed knowledge and verses (collectively known as the "Quran"). this move helped preserve the message of islam. during the expansion of the Islamic state the Quran reached many regions of the world, which had slightly different understanding of its contents and thus had different interpretations. this led to the manifestation of different schools of thought and the development of law through their teachings as applied by the rulers of the land.
