I refer to the letter First-century Arab Christians used 'Allah' .

For us Hindus, God is variously called 'Baghwan', Iswara, Sri etc.

God is called differently in different languages, culture and religions but they all still mean God and not a particular prophet.

In fact even 'Abraham' is seen as a variation of the Hindu 'Brahma' in some circles which then brings Hindusim and the Christian/Islamic/Judaism religions much closer than previously thought.
