311. When Amir al-mu'minin, peace be upon him, came to Basrah he sent Anas ibn Malik to Talhah and az-Zubayr to make them recall what he (Anas) himself had heard the Messenger of Allah, peace be upon him and his descendants, say concerning them both, but he avoided doing so and when he came back to Amir al-mu'minin, he said that he had forgotten that matter. Thereupon, Amir al-mu'minin, peace be upon him, said: If you are speaking a lie Allah may afflict you with white spots (leucoderma) which even the turban may not cover.
