Isn’t Ijma And Tawatur Just Opinions?
Ijam o tawattur does necessarily transfer the true practice to the next generations but there was no better way in the era of no printed books. For example, tarawi prayers is an addition to the rituals and we know it from a the history (a single source narration). You cab see how a single source info can change ijam o tawatur. Ijam o tawatur was useful only when there were not documented history — now we have recorded and verified history that we can and we are already using to correct ijma o tawatur practices.
True. Given he has a good reason to conclude that the chances of false practice are greater than the chances of truth. In my view the chances of prayer not being fard are very very slim. We cannot justify it to God if we begin ti skip it fir being skeptical about it
