Hence, the positive evaluation that you have of the Shi'i hadith-reports, I do not share. In all likelihood, extremist Shi'is, for whatever reasons, after having accepted the narratives about the Mahdiism, must have fabricated traditions in support of their views and ascribed them to the Prophet. The evidence for my contention is that the traditions about the Mahdi are recorded only in your Shi'i books. There is no trace of these in our authentic -- Sihah -- compilations.
