Do you differentiate between respectful and disrespectful use of Allah's name? Is it OK to use Allah's name in the same way as many say "Oh, my God!" or "Gosh" just because they are surprised?
As an Arabian we actually say 'ya Allah' a lot for different situations, so I think it's fine to say 'oh, Allah' and I am sure you will not use Allah name in inappropriate situations.
As Salam Aleikhum brother. We should use the name of God (Allah ) respectfully and not unnecessarily as it is said we should not use the name of God (Allah )in vain but in respect.Regarding (Oh my Gosh) it is not the name of God it Is an expression.
