Know that the Muhammadan leaders are of two types: the poles after his mission and the poles before his mission. The poles who were before his mission are the messengers, and they are three hundred and thirteen messengers. As for the poles from his nation who were after his mission until the Day of Resurrection, they are twelve poles, and the two seals are outside of these poles, so they are from the isolated ones. The seal will be mentioned at the end of the book, and after this chapter the twelve poles will be mentioned in full, God Almighty willing .
