To understand the Islamic religion it s not necessary to venture into the study of the religion. Others have done the research and we can reap the benefits of their study.
Muhammad himself told us where He got His revelation.
He said that His God Allah was the best “deceiver”, Surah 3:54. Christianity would call Muhammad’s God the “Father of lies””, John 8:44.
Joh 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
The use of deception is a doctrine of Islam and this should be remembered when approaching this cult from a study basis as the following linked video will show.
