People will be called by their mother's names

He said: Abu Bakr Muhammad b. Umar al-Je'abi, reported to me from Abu Abdillah Ja'far b. Muhammad al-Hasani, who reported from Ahmad b. Abd al-Mon'em, who reported from Abdullah Ibn Muhammad al-Fazari, from Ja'far b. Muhammad, from his father, peace be upon them all. And he said that Ja'far b. Muhammad al-Hasani reported from Ahmad b. Abd al-Mon'em, who reported from Amru b. Shimr, from

Jabir al-Jofi, from Abu Ja'far Muhammad b. Ali, peace be upon him, from Jabir b. Abdillah al-Ansari, who said: 

The Prophet, peace be upon him and his progeny, said to Ali b. Abi Talib, peace be upon him: "May I not give you glad news? May I not award you?" He said: "Yes, O  messenger of Allah." He (i.e. the Prophet) said: "Surely, I and you are created from one clay, and from what remained, our Shias were created. When the Day of Reckoning will dawn, all people will be called by their mother's names, except your Shias, who will be called by the names of their fathers, confirming their legitimacy."
