 Tayyeb's claim to the imamate was endorsed by the "Hurrah al-Malika" ("the Noble Queen") Arwa al-Sulayhi, the Queen of Yemen, who created the office of the Dai al-Mutlaq to administer the community in the Imam's absence.Zoeb bin Moosa (d.546 AH/1151 CE) was the first Dai-ul-Mutlaq, and lived and died in Haus, Yemen.Tayyibis (which include the Dawoodi Bohra) believe the second and current period of occultation ("satr") began after Imam Tayyeb went into seclusion and Imam from his progeny is very much present as Mahdi on earth every time.
