H 260 - Shaykh Tusi says: I found in an old book written in Ahwaz in Muharram of three hundred and seventeen. It narrated on the authority of Abu Talib Jurjani: While I was in Qom, there began a discussion amongst our people about a man who had negated his son to be from his seed. They sent a man to Shaykh Siyanatullah, as I was present before him. The messenger handed to him the letter, but he did not read it and told him to go to Abu Abdullah Bazufari for the answer. I went with the messenger. Bazufari said to him, “The boy is his son and he copulated with his mother in such and such day in such and such time. Tell him to name his son Muhammad.” The messenger returned and the matter was clarified to all and the boy was named Muhammad.
