Abu Al-Ash'ath San'ani says that once Yazid sent us to Abdullah bin Zubair (may Allah be pleased with him). When I reached Madinah Munawwarah, I also visited a certain person whose name the narrator forgot, and said, "You can see what people are doing. What is your opinion regarding this matter?" He replied, "My close friend Abu Al-Qasim (peace and blessings be upon him) advised me that if you encounter a time of tribulation, go to Mount Uhud and strike the edge of your sword on it, then sit in your house. If someone enters your house, go into your room. If he comes there as well, then bend down on your knees and say, 'Take both my and your sins and go back, so that you become among the people of Hellfire, and that is the recompense for the wrongdoers.' Therefore, I have broken the edge of my sword and am sitting in my house."
