Reference for Hadith?

i would like to find a hadith i cannot find. It goes like A man comes to the prophet (ﷺ) and he says he would accept Islam however he won't do a certain part of the Salah ( He won't do Sujud/Do Ruku?) and the prophet (ﷺ) accepts. I'm 99% sure this hadith exists in some form like this but I cannot find it online. I apologise if this too vague but this is what I remember
