I have read in forums online that the modern day Shia faith is distorted from the one espoused by classic scholars like Saduq, Mufid, etc. How can we explain the present day Shia faith and the difference from early Shia islam. Are some/most of our practices based on weak sources and fabrications and have we abandoned the Shia Islam as it was meant to be practiced for a one filled with Ghulluw and Bida?

Our Shia faith is preserved by our scholars from generation to generation.
