Aban was afflicted by some paralysis and when a man who heard the tradition began to look at him, he said to him: Why are you looking at me? I swear by Allah, I did not tell a lie about Uthman, nor did Uthman tell a lie about the Prophet (ﷺ), but that day when I was afflicted by it, I became angry and forgot to say them.
