At their cores they are not similar as there are major theological differences especially between Judeo-Christians and Islam.
In Judeo-Christianity, there is an 'intimacy' revealed by God to His Creation (see Deuteronomy 1:31; Isaiah 40:11; Jeremiah 3:14 to list a few). We are even told to call Him 'Father' (see Matthew 6:8, et al). This is not the case in Islam. The Judeo-Christian God is presented as a God of Love - as the initiator and for all mankind, even sinners. The Qur'an has numerous places that say God does not love the sinner (see Deuteronomy 7:7; and John 3:16 versus Sura 2:190 and Sura 3:57 as examples).
For Islam, God is unknowable (see Sura 40 as example) while in Judeo-Christianity, God reveals Himself in many ways to His Creation (see Jeremiah 9:23-24 and John 17:3 as examples). These are just some of the differences between the religions.
They're similar in the fact that they have one god (Allah in Islam, Yahweh in Christianity.)
Christianity, Islam, Judaism & even Baha'i all have a mutual ancestor: Abraham.
Christianity, Judeaism, and Islam are similar. they believe in the same God and have a shared History. the Story splits with Abraham.
