Religion Islam has started from Adam( a.s) and completed with our Beloved Prophet Muhammad (saww) so Prophet Adam (a.s), Noah (a.s) Ibrahim (a.s) Musa(a.s) and Isa (a.s) all they were Muslims. Therefore what names they have used at their time in their language for Allah or God are the same. But if today Jews and Christians they mean different meaning by Using Yehweh or God with Allah as they say differe qualities about the God then it would be different from what we Muslims meant by Allah and His Holy Attributes otherwise Yahweh of Moses (a.s) is the same as Allah what Prophet Muhammad (saww) has said.
