Shu'ba reported from Habib: While we were in Medina we heard of plague having broken out in Kufa. 'Ata b. Yasir and others said to me that Messenger of Allah ﷺ had said. If you are in a land where it (this scourge) has broken out, don't get out of it, and if you were to know that it had broken (in another land, then don't enter it. I said to him: From whom (did you hear it)? They said: 'Amir b. Sa'd has narrated it. So I came to him. They said that he was not present there. So I met his brother Ibrahim b. Sa'd and asked him. He said: I bear testimony to the fact that Usama narrated it to Sa'd saying: I heard Messenger of Allah ﷺ as saying that it is a God-sent punishment from the calamity or from the remnant of the calamity with which people were afflicted before you. So when it is in a land and you are there, don't get out of it, and if (this news reaches you) that it has broken out in a land, then don't enter therein. Habib said: I said to Ibrahim: Did you hear Usama narrating it to Sa'd and he was not denying it. He said: Yes.
