This exultation plainly betrayed the disposition of his race; and though Sám smiled at the extravagance of Mihráb, he looked up towards Heaven, and prayed that Rustem might not prove a tyrant, but be continually active in doing good, and humble before God. Upon Sám departing, on his return to Karugsár and Mázinderán, Zál went with Rustem to Sístán, a province dependent on his government, and settled him there. The white elephant, belonging to Minúchihr, was kept at Sístán. One night Rustem was awakened out of his sleep by a great noise, and cries of distress when starting up and inquiring the cause, he was told that the white elephant had got loose, and was trampling and crushing the people to death. In a moment he issued from his apartment, brandishing his mace; but was soon stopped by the servants, who were anxious to expostulate with him against venturing out in the darkness of night to encounter a ferocious elephant. Impatient at being thus interrupted he knocked down one of the watchmen, who fell dead at his feet, and the others running away, he broke the lock of the gate, and escaped. He immediately opposed himself to the enormous animal, which looked like a mountain, and kept roaring like the River Nil. Regarding him with a cautious and steady eye, he gave a loud shout, and fearlessly struck him a blow, with such strength and vigor, that the iron mace was bent almost double. The elephant trembled, and soon fell exhausted and lifeless in the dust. When it was communicated to Zál that Rustem had killed the animal with one blow, he was amazed, and fervently returned thanks to heaven. He called him to him, and kissed him, and said: "My darling boy, thou art indeed unequalled in valor and magnanimity."
