who follow the Apostle - the illiterate prophet, whom they find written down with them in the law and the gospel, bidding them what is reasonable and forbidding them what is wrong, and making lawful for them what is good, and making unlawful evil things; and setting down for them their burdens and the yokes which were upon them; - to those who believe in him and aid him and help him and follow the law which has been sent down with him - they shall be the prosperous.'
