Surely We revealed the Taurat in which was guidance and light ; with it the prophets who submitted themselves ( to Allah ) judged ( matters ) for those who were Jews , and the masters of Divine knowledge and the doctors , because they were required to guard ( part ) of the Book of Allah , and they were witnesses thereof ; therefore fear not the people and fear Me , and do not take a small price for My communications ; and whoever did not judge by what Allah revealed , those are they that are the unbelievers .
