Usama bin Zayd and Saad were sitting together talking, and they said that the Messenger of Allah ﷺ said, "If you are in a land where it breaks out, do not leave it, and if you hear that it is in a land, do not enter it."Habib said, "I asked, 'On whose authority?'"They replied, "On the authority of Amir bin Saad, who narrates it."Habib continued, "So I went to him, but they told me he was away. Then I met his brother Ibrahim bin Saad and questioned him."Ibrahim said, "I was present when Usama was telling Saad, 'I heard the Messenger of Allah ﷺ say, "This affliction is a scourge, or a punishment, or the remnant of a punishment with which people before you were punished. So if it is in a land and you are in it, do not leave it, and if you hear that it is in a land, do not enter it."'"Habib said, "I asked Ibrahim, 'Did you yourself hear Usama telling this to Saad, and Saad did not object to it?'"Ibrahim answered, "Yes."
