[1][2] A tradition by Ja'far al-Sadiq about Yamani ancestry said, "[One] from the lineage of my uncle Zayd will rise from Yemen.
[5] Additionally, some sources call al-Yamani "Mansour" and that he will assist Muhammad al-Mahdi al faizz in battle.
One rises from Yemen whom wont support the promised Mahdi, but will fight Sufyani and finally die.
"[10] In another Hadith, Ali al-Ridha said, "[t]he rise of Sufyani, Yemeni, and Khorasani will be at the same year, month, and day.
[13][14] While traditions provide few details about the conclusion of Yamani's appearance, a hadith by Muhammad al-Sadiq is said, "[a]fter the numerous wars and failures, he will crush the Sufyani and kill him.
