Who and when did this bid'ah for the first time in adhan?

In Sunni Islam adhan (اذان) is as follows: > اَللهُ اَکبَر (4 times) > > اَشهَدُ اَن لا اِلَهَ اِلَّا الله (2 times) > > اَشهَدُ اَنَّ مُحَمَّد رَسُولُ الله (2 times) > > حَیِّ عَلَی الصَّلاة (2 times) > > حَیِّ عَلَی الفَلاح (2 times) > > حَیِّ عَلَی خَیرِالعَمَل (1 time) > > اَللهُ اَکبَر (2 times) > > لا اِلَهَ اِلّا الله (2 times) But in Shia Islam there are execssive parts between two of the parts: > اَشهَدُ اَنَّ مُحَمَّد رَسُولُ الله (2 times) > > **اَشهَدُ اَنَّ عَلِی وَلیُ الله** (1 time) > > **اَشهَدُ اَنَّ عَلِی حُجَّةُ الله** (1 time) > >حَیِّ عَلَی الصَّلاة (2 times) The adhan that was recited by the Prophet Muhammad (P.B.U.H.) and his companions clearly was the Sunni version. But somewhere in history Shiites did this bid'ah in adhan. Now in Iran I know the Shiite version is recited. Who and when did this bid'ah?
