   1.    The Names of the Twelve Imams of Ahlulbayt (A.S.) were mentioned by the Prophet Muhammed (P.B.U.H. and His Holy Progeny) in many authentic Hadeeths narrated in Shia Books and Sunni Books as well. Despite all the efforts of the enemies of Ahlulbayt (A.S.) to delete and hide and destroy any written Hadeeth in favor of Ameerul Mo'mineen (AS.) and Ahlulbayt (A.S.). You find till today many of Sunni Books still contain many Hadeeths in favor of Ahlulbayt (A.S.).

All Muslims believe that the Prophet (SAWA) has said that: My Successors will be twelve. This Hadeeth of Twelve Successors is mentioned in:

    ⁃    Al-Albani in Takhreej al-Hadeeth; 376, 1075 and 3598.
    ⁃    and in many other Sunni Books. The Hadees states that all the twelve will be from “Quraish”.
