Incremental Knowledge
It’s not correct to draw parallels between science and religion in this regard. Science is a knowledge of discovery of this universe. As we continue on the path of this discovery, our ideas are bound to evolve. Religion, on the other hand, is about a news of an incident that’s about to take place – the day of judgement. It addresses what will happen after death and how we should prepare for it. The knowledge of religion was last given to the humankind by prophet Muhammad SAW, so it’s fair to think that those who were the closest to him understood it the best. There are, however, natural differences amongst sahaba, but our aim should be to try to best establish what prophet SAW gave people as religion, understand it in light of the Quran, and sincerely adopt it as our viewpoint and practice.
