The concept of God as father is very much a Christian one rather than a Judeo-Christian one. What all the Abrahamic religions have in common is the concept of God as, to quote Stim, "a higher authority to whom we can always appeal to justice".

Muslims of course see their religion as the authentic continuation of that of Abraham, with Judaism and Christianity as departures from that tradition. Similarly Christians have often seen Islam as a breakaway from Christianity. The three traditions are very entangled, and have a great deal in common.
