By its standard have been judged the Jews , by the prophets who bowed ( as in Islam ) to Allah 's will , by the rabbis and the doctors of law : for to them was entrusted the protection of Allah 's book , and they were witnesses thereto : therefore fear not men , but fear me , and sell not my signs for a miserable price . If any do fail to judge by ( the light of ) what Allah hath revealed , they are ( no better than ) Unbelievers .
