The Chachnāma (Fatḥnāma-yi Sind) 16.2.8

16.2.8

When a fox is tired of waiting for its victim, it makes believe it is dead, in order that carrion-eaters might collect (to eat its apparently dead body). Then it jumps up, and catches them, and eats them. A king should never consider himself safe from an enemy. You had better send a confidential servant first to investigate and to enquire, so that the truth may come out.” Accordingly a trustworthy person was despatched (to Daharsiah’s camp). He found all his grandees and nobles in sorrow and mourning, according to the custom of the time. He approached them and said: “I am sent by king Dahar to enquire after the health of Daharsiah, and I see you all mourning; pray, what is the matter?” Two of the nobles arose, and led him to where Daharsiah was lying, in order that he might see for himself. (Finding that Daharsiah was dead) he expressed great grief. The nobles gave Daharsiah’s ring to the messenger as a proof of the truth of the sad news, and sent him back. When the messenger communicated the sorrowful news to Dahar and gave him the ring, the latter, without any more thought or delay, came out with all his friends and nobles, and, crossing the waters of the Mehran, arrived at the camping ground. He entered his brother’s tent, and, when he saw him (lying dead), he tore his clothes (out of grief), threw off his turban, and took to mourning with cries and groans.
