We travelled with God's messenger, and when we alighted in a broad wadi God's messenger went to relieve himself, but could find nothing with which to screen himself. There were two trees at the side of the wadi, so God's messenger went to one of them and, taking hold of one of its branches, he said, "Allow yourself to be led by me, with God's permission." Then it was led by him like a camel with a piece of wood in its nose which is amenable to the one who guides it, until he came to the other tree. Then taking hold of one of its branches he said, "Allow yourself to be led by me, with God's permission," and it was led similarly. Then when he was in the middle between them, he said, "Draw close together about me, with God's permission," and they did so. I sat occupied with my thoughts, and when I turned round, I saw God's messenger coming, and noticed that the trees had separated, each standing on its own trunk. Muslim transmitted it.
