Step-by-step explanation:
Islamic teaching, and especially the spreading of Islam, particularly after the death of the Prophet, became the responsibility of Islamic missionaries, almost like Christian missionaries, and they were known as Dawahs, since their only purpose was to move from place to place spreading the truth of Islam, and the Qu´ran. These missionaries, from the 7th century onwards, spread really fast from the Arabic Peninsula by accompanying merchants, and Arabian conquerors and warriors, in their quests. Another way that these Dawahs were able to spread Islam was through land exploration.
