Are introductions in other languages suitable for internet videos?
Firstly, I don't know if this is on-topic or not; I'll leave it for others to decide.

Simply, there are no rules. The question I would ask, is "would you do this in person?". That should give you your answer.

It intrigues me, however, that you wish to use a phrase from a culture and religion you are not a part of - so you really need to be extremely careful that you understand the implications of the phrase, as well as if it is used within society by non-Muslims. Cultural appropriation can be a serious insult to a culture; or it can be seen as appreciative and continuing their history.
