This document provides an introduction to the concept of Iman (faith) in Islam. It discusses how knowledge is the first and most important step towards becoming a true Muslim. Simply being born into a Muslim family or verbally professing Islam is not enough - one must have conscious knowledge and understanding of Islamic teachings from the Quran and Prophet Muhammad. Without knowledge, one cannot properly distinguish between Islam and disbelief, and risks losing their faith through ignorance. The document urges Muslims to spend at least an hour each day acquiring religious knowledge in order to strengthen and preserve their Iman.
