Hazrat Ubayyah narrates that once, in the presence of Hazrat Ibn Umar (may Allah be pleased with them), a camel became unruly. A man wanted to slaughter it by nahr, but he was unable to do so. Hazrat Ibn Umar (may Allah be pleased with them) said, "Take the name of Allah and strike it with a spear in its side." He did so. A piece of meat was taken from that camel, which Hazrat Ibn Umar (may Allah be pleased with them) bought for two or four dirhams.
