I agree with Aykol on the external sources for Muslim observations and practices, some of which are today viewed as objectionable. But he doesn't go far enough.
What is that you want him to say Unifier? suppose you were him.,what will you say about Islam??
Islam is entirely drawn from Jewish, Christian and Zoroastrian sources.
by those words you are saying nothing new.,Quran itself says that
It added nothing, and distorted plenty.
Nope ., unless you show me verses of bible and verses of Quran ad compare/contrast to show the distortion I will not trust your hand waving statements .,And Sure Quran added/highlighted a very important statement That " JESUS IS NOT SON OF GOD OR GOD" whatever that god may be ...
While its source cultures and religions either matured and changed (Judaism and Christianity) or virtually died out (Zoroastrianism) Islam stuck with what it vacuumed up from 7th century Mesopotamia.
Look NOT JUST ISLAM., all the faiths stuck along with their faith heads all the way to the end of 20th century and that goes to every faith ., The fact is, 20th century logic/rational thinking of enlightened folks along with tremendous advancement in science and technology made western Jews and Western Christians to calm down and control faith heads by the use of
that fundamental freedom of expression. I agree Muslims and Islam is far behind in the present time in that aspect..
