Short answer: No Explanation: as you know تراشیدن due to having ـَ ن at the end, is an infinitive. So your translation, After shaving my beard, is correct. As much as I know adverbial participles describe or modify a noun, verb or adjective ( please correct me if I'm wrong) But here تراشیدن expresses an action, shaving. Despite this fact, those sentences will be: بعد از "رفتن" به سر کار، چای درست میکنم and قبل از "خوابیدن" کتاب میخوانم of course I prefer translating them in other way using قبل از اینکه or بعد از اینکه: قبل از اینکه بخوابم کتاب میخوانم and بعد از اینکه به سر کار میروم چای درست میکنم (just for more info :)) Hope that helped you :)

The Persian sentence you made is grammatically correct. But the verb "taraashidan" doesn't function as an adverbial participle in this sentence. In other cases when the verb indicates a movement, it is more common to conjugate the verb rather than using an infinitive, like the examples Raena has provided. Using advebial participle is common in the Engliah equivalents of such sentences. But I think the following sentence is a little bit different. Have a look: "I brush my teeth before going to bed." ... In Persian, we usually say: قبل از خوابیدن دندان هایم را مسواک میزنم (This example is what you're looking for, I suppose) It's not very common to say: قبل از اینکه به رختخواب بروم دندان هایم را مسواک میزنم We, however, may say: قبل از اینکه بخوابم دندان هایم را مسواک میزنم Hope I helped you not confused you! ;-)
