12-5 Al-Hassan ibn Abdullah ibn Sa’id al-Askari narrated that Abul-Hussein al-Nesabat Muhammad ibn al-Qasim al-Tamimy al-Sa’edi quoted Abul Fazl Ja’far ibn Muhammad ibn Mansoor, on the authority of Abu Mahkam Muhamad ibn Hisham al-Sa’edi, on the authority of Ubaydullah ibn Abdullah ibn al-Hassan ibn Ja’far ibn al-Hassan ibn al-Hassan ibn Ali that he asked Ali ibn Musa ibn Ja’far Al-Ridha (MGB) regarding what is said about the Al-Aftas clan. The Imam (MGB) said, “The Honorable the Exalted God brought about twelve clans from the Children of Israel - that is Jacob the son of Isaac the son of Abraham (MGB). God established Prophethood and the Book amongst them. God also generated twelve clans from the progeny of Al-Hassan (MGB) and Al-Hussein (MGB) - the sons of the Commander of the Faithful Imam Ali (MGB) and the Blessed Fatimah (MGB) who was the daughter of God’s Prophet (MGB).” Then the Imam (MGB) added by naming the twelve clans from the Children of Israel as follows, “Reuben - the son of Jacob; Simeon - the son of Jacob; Judah - the son of Jacob; Isaac - the son of Jacob; Zebulun - the son of Jacob; Joseph - the son of Jacob; Benjamin - the son of Jacob; Naphtali - the son of Jacob; Dan - the son of Jacob.”He (MGB) added, “And six clans were brought about from the progeny of Al-Hassan (MGB). They are the clan of Al-Hassan ibn Zayd ibn al-Hassan ibn Ali; the clan of Abdullah ibn al-Hassan ibn al-Hassan ibn Ali; the clan of Ibrahim ibn al-Hassan ibn al-Hassan ibn Ali; the clan of Al-Hassan ibn al-Hassan ibn al-Hassan ibn Ali; the clan of Davood ibn al-Hassan ibn Ali; and the clan of Ja’far ibn al-Hassan ibn al-Hassan ibn Ali. All the progeny of Al-Hassan ibn Ali (MGB) come from them. Then he (MGB) counted the clans brought about from Al-Hussein ibn Ali (MGB) as follows: the clan of Muhammad ibn Ali al-Baqir ibn Ali ibn al-Hussein; the clan of Abdullah ibn al-Bahir ibn Ali; the clan of Zayd ibn Ali ibn al-Hussein; the clan of Al-Hussein ibn Ali ibn al-Hussein ibn Ali; the clan of Umar ibn Ali ibn al-Hussein ibn Ali; and the clan of Ali ibn Ali ibn al-Hussein ibn Ali. These are the six clans which the Honorable the Exalted God brought about from Al-Hussein ibn Ali (MGB).”
