Page "Islamic conquest of Afghanistan" Paragraph 11

During the 8th through the 9th centuries, many inhabitants of what is present-day Afghanistan and western Pakistan were converted to Sunni Islam.

In some cases, however, people that were conquered by the Muslims would rebel and revert to prior forms of worship.

The mountain areas were still not completely converted and remained largely by people of non-Muslim faiths.

In a book called Hudud-al-Alam, written in 982, it mentions a village near Jalalabad, Afghanistan, where the local king used to have many Hindu, Muslim and Afghan wives.
