Sayyidah Fatimah bint Qays (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) addressed us at a time when he (peace and blessings be upon him) did not usually address us, and he said: "I have addressed you at this time only because of news that has reached me. Tamim al-Dari has told me that his cousins sailed on the sea, and their ship broke up at an island in the sea. There they found a beast. They asked: What are you? It said: I am al-Jassasah." And the narrator narrated the hadith in full.
