Deviation of the Ummah: Past and Present
"Throughout time man has deviated. The people who were alive during the time of the prophets before the Prophet Muhammad (saw) deviated just as those who are alive now deviate. So, as a result deviation is nothing new. However, we may extract benefit from the mistakes of the past. This presentation is meant to inform us of the various types of deviation which have occurred, so their mistakes will not be repeated. This lecture is also a source of historical reference material."
