Abu al-Malih al-Hudhali (may Allah have mercy on him) wrote to Abu Ubaydah bin Abdullah bin Mas'ud (may Allah be pleased with them both) about a muhrim who harms a wild ass, an ostrich or an ostrich egg, and about a locust that a muhrim kills. He wrote back in reply: If a muhrim kills a wild ass, then the sacrifice of a camel is due for it; for an ostrich, the sacrifice of a camel; and for an ostrich egg, one day's fast or feeding a needy person. As for the locust, a man from the people of Hims killed a locust while he was in the state of ihram. He asked Sayyiduna Umar (may Allah be pleased with him), and Sayyiduna Umar (may Allah be pleased with him) asked: What have you paid as compensation for it? He said: I have paid only one dirham. He (may Allah be pleased with him) said: O people of Hims! You have a great many dirhams; a date is dearer to me than a locust.
