A group of these traditions establishes that the first of them is Ameerul Momineen Ali Ibn Abi Taalib (a.s.) and the last of them is the Mahdi (a.s.). Another group proves that the first of them is Ali (a.s.), the second Hasan (a.s.), the third Husain (a.s.) and the remaining nine are from the progeny of Husain (a.s.). Yet another batch establishes that the ninth from the progeny of Husain (a.s.), is the twelfth Imam, the Mahdi (a.s.).
A number of these traditions guide towards the names of the twelve Imams, and introduction of their personalities. There are numerous another traditions that explain, in brief or in detail, tidings about the twelve Imams (a.s.). Obviously, the wise and logical approach in comprehending the purpose of these traditions is to derive their meanings and implications. The weakness of the chain of narrators in a few of them shall not affect their validity due to the strength and reliability of others.
For, the strong and reliable chains do away with the infirmness of the weak ones. Often, we shall demonstrate this reality in the course of our explanations, Inshallah. Thereafter, we shall ponder on the group of traditions that establishes that the number of Imams is twelve. With which Islamic sect is this number compatible? Or, is compatibility found at all in any of the sects? Or, shall we say, God forbid, that these traditions did not actually occur in reality?
We say: Know that the discussion concerning this group of traditions is divided into two levels: First: The meanings and implications of these traditions. Second: Determination of those on whom these traditions apply. In other words, the recognition of the twelve caliphs along with their personalities. The First Level: The Meanings And Implications Of These Traditions First: The number of the caliphs, who shall succeed the Messenger of Allah (s.a.w.a.) is confined to twelve.
None can increase or decrease any one of them. This is the gist of each one of these traditions. Second: The endurance of the earth and its protection from disorder is dependant on the survival of the Imams (a.s.). Third: Non-termination of Islam before their (Imams a.s.) termination i.e. the continuity of Islam depends on them.
As long as even one of them lives, Islam will continue to endure and prosper, which proves their prolonged stay on the earth, even if it means the longevity of the twelfth and the last one of them.
