Is saying 'Ya Muhammad', or 'Ya 'Alee' Shirk?

[The Shah]

Salam

I Just wanted to ask ... is the saying YA MUHAMMAD pbuh or YA ALI ra

is this considered as shirk ...

i now its recommended that you really only say YA ALLAH as hes the greatest he created all these beings and that muhammad and ali cant help you however

some muslims claim that your askin allah to accept your dua in the sake of the prophets/sahabah/imams ...

So is it best if i just stay away from YA MUHAMMAD YA ALI buisness or is it someat im fine saying ?

help ?

W.salam
