"The people of Moses got themselves into 71 sects of which one was on the right and the rest on the wrong. The people of of Jesus divided themselves into 72, of whom only one had been on the right and the rest on the wrong. And the people of my faith will be divided into 73 groups of which only one will be on the right and will be saved, and the rest will be on the wrong."
