During his thirteen-year career as a preacher, Mohammed converted approximately 150 people to Islam in Mecca. Within the course of ten years of jihad (following his migration to Medina), Mohammed spread Islam throughout Arabia. The fact that the Islamic calendar starts with Mohammed's immigration to Medina and not with his birth, death, or the first Koranic revelation indicates the significance of this event for the success of Islam.
|Growth of Islam in Mecca and Medina|
- Muslims are part of the Islamic nation, called the Ummah, wherever they live.
- Life in non-Islamic countries is undesirable, but possible, if the migrant behaves as an exemplary Muslim.
- Each migrant is obliged to constantly strengthen his religious identity and keep their distance from everything contradictory to Islam. In order to strengthen his religious identity, he should build mosques and be their benefactor, as well as set up Muslim schools, cultural centers and shops.
- Each migrant is supposed to promote the objectives of the Muslim community, both in the religious and the political field and he shall not make difference between those two.
- Muslims in the West are supposed to spread Islam in the declining and spiritually void Western societies.
