Zohre and Tahir.

An Eastern shah and his vizier have no heirs. One day, they go hunting, intending to shoot a roe deer. At the last moment, the vizier notices that the doe was about to give birth, and the shah decides to spare the animal. That same night, the shah and the vizier have the same dream: it is as if the doe has foretold to them that both would soon have heirs.
