How is islam similar to judaism?

Answer 1

Well, both Judaism and Islam insist that there is only one God. Of course, the two faiths have very different ideas about whom this God favors and what He expects in the way of worship. It's kind of as though people in the 31st Century agreed that the US elected a President in 2001, but some thought it was George Bush and some thought it was Al Gore.

Answer 2

Both Jews ans Muslims worship same God; the one and only one God with no partner, no companion, no son, no father, no associate, and no equivalence.

Answer 3

There is no fundamental difference between the Jewish concept of God and the Islamic Concept of God. Both hold that God is a singular entity who created the universe, is the basis for morality, who requires orthodox belief and orthopraxis. There are certainly differences in the components of religious practice and the orthodoxos, but the God-concept is almost exactly the same.
