How was islam spread to different parts of the Word

At the beginning of CE 7th century, Islam was founded in Mecca and Medina.

Explanation:

The conquest of land and of the migration of Islamic leaders and their families spread to the southeast of India, first by Muslim trades people on the biggest trade road from China to Far East, was then later extended by Sufi orders.

Throughout the North of Sumatra (Aceh), the first settlements appeared and Malacca became a center of Islam and expanded along the trade routes of this area. There is no clear sign of the first Muslim gravestone marks coming into this region since Islam first reached the region throughout 1082.

In Malacca, we can see that the dynasty first appears in the type of Sultanate of Malacca into the far end of the island by the transition of one Parameswara Dewa Shah to a Muslims and the takeover of its name Muhammad Iskandar Shah after his marrying to a princess of a Buddhist area, which usually followed traffic roads in the east, and a half-century later.
