As far as I know (I heard in a speech by Shaykh Salman Nadwi), There are many shiah narrators of hadith in reliable sunni books and being a shiah is not enough criterion to label a hadith fabricated. However, their narration are not taken when they go against the beliefs of Ahl-us-sunnah.
wallahualam.

Bro, What I have heard/read is that shias can be a part of the sanad(chain) of a reliable hadith [Can someone confirm this, i m not sure about this even] . Thats not the issue here.

BUT

Shias have hadith of their own. Most of them is start like Imam Jafar said... or Imam Fulan said... without any sanad. I m not disregarding the authenticity of Imam Jafar (ra) but the Shias have falsely attributed many hadith to Him WITHOUT a proper sanad to Rasoolullah or the Sahabah.

If you look closely the hadith in question, is there a source for it? Is it mentioned any of the Hadith collections?
