Prophet (S) had said: “Allah the Almighty has chosen a thing from every thing. He has chosen Mecca from the earth, the mosque from Mecca and the place, in which the Kaaba is, from the mosque. He has chosen the females from among the cattle and the ewe from among the sheep. He has chosen Friday from among the days, Ramadan from among the months and the Night of Predestination from among the nights. He has chosen the Hashimites from among the peoples, has chosen me and Ali from among the Hashimites, has chosen al-Hasan and al-Husayn from me and Ali and then He completed the twelve imams from the progeny of al-Husayn. The ninth of them (of al-Husayn’s progeny) is the hidden and the apparent and the best of them. He is the expected imam.” The same was narrated by Muhammad bin Hammam and Muhammad bin al-Hasan bin Muhammad bin Jumhoor from al-Hasan bin Muhammad bin Jumhoor from Ahmad bin Hilal from Muhammad bin Abu Omayr from Sa’eed bin Ghazwan from Imam Abu Abdullah as-Sadiq (as).
