Musannaf Ibn Abi Shaybah 27612 — Cursing an animal

Abu Uthman said: While Sayyiduna Umar (may Allah be pleased with him) was traveling with his companions, there was among the people a man traveling on a camel of his, which he would steer wherever he wished. I do not know what difficulty it gave him, but he cursed the camel. At this Sayyiduna Umar (may Allah be pleased with him) asked: "Who is this one who cursed?" The people said: "So-and-so." He said: "You and your camel stay behind, away from us. We will not keep a cursed mount with us."
