I would disagree here. Yahweh in the Torah and the books of Joshua and Judges (and you're probably not thinking of the Yahweh of the latter prophets who condemned Israel for failing to take care of the poor, orphans, widows, and oppressed) was a tribal god who loved his people, Israel, and no one else; yet a jealous one which hated other gods, and that was what made him different from the like of Ba'al. But he was NOT a universal god who wanted all people to worship him; he was Israel's and Israel was his. Allah in the Quran is the Late Antique Christian god, he is the god of all peoples in all place and he does not want anyone to worship any god but him, no matter where they are. He is not only jealous of his people, the believers (mu2min is user more than muslim in the Quran itself, and there's good reason to believe that the early proto-Muslims called themselves mu2min and muhaajir not muslim), but he is also intolerant of any god being worshipped anywhere in any way but that proscribed in the Quran and by the prophets. This idea can be found later in the Tanakh, mainly in Isaiah, but even there god does not want to convert the unbelievers, he just wants Israel to triumph over them through the coming of the Messiah. The vindictive Yahweh that ordered the Israelites to slay the Amalikites to the last man, woman, and child can be seen in the "sword" verse etc., but his aim is quite different. In the Torah, Joshua and Judges Yahweh wants to ethnically cleanse Palestine of its people to make way for the Chosen People, in the Quran Allah wants to terrorize the unbelievers into accepting the rule of the believers and eventually accepting their religion. It's a crucial development IMO.
Well put - thanks
