What is ruling of darood tanjina

I have heard some people talk about a Darood called Darood Tanjina, to recite in Quran Khawani (in south asia like pakistan ppl gather to read quran). I can't find a reference of that Darood on net, what I found is according to this video it is a Bidah . if It is a innvoation why people read it thinking it will bring tranquality? Edit: for reference, what it is, I found it here (not confirmed personally if it or not but word tanjina occur in it)
