I wouldn't recommend doing this, as the paper has not yet been accepted.
You are not sure if that paper will actually be published in that journal - so what source will you reference?
Best to wait until you have confirmation that it will be accepted (even if further revisions are needed) - you could then be sure it will come out in that journal.
My understanding aligns with Samantha's. Only cite before publication when accepted, then use the standard format for the citation, and write after the [YEAR]: in press.
I agree with Samantha Curle, you should only include a paper in the reference list if you are completely sure it will be published. But you can provisionally cite an unpublished work as a MS in preparation (for example, "Saxena et al., manuscript in preparation"). This will give you some time until you hear back from the journal.
A paper has a life once it is finished with writing:
- in submission: only use when the editor confirms receipt of your paper, should not really be used at all in my view
- in review: only use when the editor sends the reviews back to you, and in my view, this is the key moment to cite your own work IF the paper is accepted with revision
- in press: after you have returned the modulated, revised ms
