Abu Huraira said God's messenger told that while a man was driving a cow, he grew weary and mounted on its back, whereupon it said, "We were not created for this, but only for tilling the ground." The people said, "Glory be to God! Can a cow speak?" and God's messenger replied, "I believe it, as also do Abu Bakr and `Umar, but they were not present at the time. He then told that while a man was shepherding some sheep of his, a wolf attacked one of them and seized it. Its owner caught up on it and rescued it and the wolf said to him, "Who will look after it when the beast of prey's day comes and it has no shepherd but me?" The people said, "Glory be to God! Can a wolf speak?" and he replied, "I believe it, as also do Abu Bakr and `Umar," but they were not present at the time. (Bukhari and Muslim.)
