Abu Burda told on his father's authority that he, meaning the Prophet, raised his head to the sky, which was a common practice of his, and said, "The stars are a means of safety for the sky, and when the stars depart what the sky has been threatened with will come to it. I am a means of safety for my companions, and when I depart what my companions have been threatened with will come to them. My companions are a means of safety for my people, and when my companions depart what my people have been threatened with will come to them." Muslim transmitted it.
