Jawamiʿ al-hikayat wa lawamiʿ al-riwayat 36: A Rare Animal.

36

II. xiiii. 4.
Abú Ríhán mentions in his writings that within the boundaries of Hindústán, to the east of the Ganges, in the forests of Oudh, there exists an animal called Sharú. It is larger than a rhinoceros, and has two long horns and a small trunk. On the back it has four protuberances resembling four feet. It is so powerful that it will attack an elephant and tear him asunder. No animal has strength enough to contend against it, nor does man venture to hunt it, in fact nothing has power over it except death. Besides natural death, one cause of its destruction is that it often takes up an animal on its horns and tosses it in the air. The flesh adhering to the horns creates worms, which falling on its back, eat into the flesh till it becomes very sore; they then attack its stomach and destroy it. Or, if there be a high mountain near, when it thunders, it will rush as if to attack (some unseen foe) and falling from the mountain destroy itself. People go out to pick up its horns. Its specific peculiarities (khdssiyat) are not known.
