Khadija was the first person Prophet Muhammad converted. She read the qalma and embraced Islam and accepted Prophet Mohammed as Allah’s messenger. This happened when prophet was 40 years old. What was his wife practicing before this happened?

Sayyida Khadija (as) was from amongst those people in Mecca who practiced a monotheistic faith. They were called Haneef, or followers of Haneef, as Haneef was one of the titles of Abraham (as).
