Jesus named the God Allah and preached Muhammad
God is the term "God" in the English language but it is not a name for the God
Allah is the term "God" in the Arabic language but also it is a name for the God
and Jesus named the God as Allah and preached about the messenger that would come after him
and named him Muhammad
you can see and hear that in this four minutes clip from a film about Jesus
