This document provides class notes on the explanation of the three fundamental principles of Islam from the Islamic College of Canberra. It discusses Iman (faith) as the second level or fundamental principle. Iman has over seventy branches, with the highest being the testimony of faith and the lowest being removing harmful objects from paths. Iman also has six pillars: belief in Allah, His angels, His books, His messengers, the Day of Judgment, and divine destiny. The notes then explain the difference between Iman and Islam when mentioned together or separately, and discuss the pillars of Iman in more detail.
