32-13 Muhammad ibn Ibrahim ibn Ishaq al-Taliqani - may God be pleased with him - narrated that Ahmad ibn Muhammad ibn Sa’eed al-Kufi al-Hamdani quoted on the authority of Ali ibn Al-Hassan ibn Fadhdhal, on the authority of his father that Abil Hassan Ar-Ridha’  said, “Why were the Best Messengers called the ‘Ulul-Azm?” The Imam  answered, ‘They were called the ‘Ulu-Azm since they had laws and regulations. The Prophets that came after Noah  all followed thelaws of Noah , and followed him. The Prophets  that came after Noah all followed his Book until Abraham  came. The Prophets  that came after Abraham  all followed Abraham’s laws. The laws and the ways of Abraham were followed by all the Prophets that came after Abraham  until Moses . Then after Moses , the Prophets followed his laws and ways and adhered to his Book until the time of Jesus . All the Prophets at the time of Jesus  and after him followed his laws and ways and adhered to his Book until the time of our Prophet Muhammad (S). Therefore, these five Prophets are the ‘Ulul-Azm and are the best of the Prophets and Messengers. The laws of Muhammad  will not be voided until the Resurrection Day. No Prophet will ever come after him until the Resurrection Day. It is incumbent to kill whoever claims Prophethood after him  or brings a book after the Qur’an for anyone who hears his claim.’”
