Anas reported God's messenger as saying, "The people will establish cities, Anas, and one of them will be called al-Basra. If you should pass by it or enter it, avoid its salt-marshes, its river front, its palm trees, its market, and the gate of its commanders, and keep to its environs, for the earth will swallow some people up, pelting rain will fall and earthquakes will take place in it, and there will be people who will spend the night in it and become apes and swine in the morning." . . . transmitted it. (The name of the source is omitted in the text. The tradition is in Abu Dawud, Malahim, 10).
