Ataa As-Sulaymee (rahimahullaah) said:

”I heard Ja’far Ibn Yazeed (rahimahullaah) mentioning that a man once went past a gathering, so they praised him with good.  When he left them, he said: ”O Allaah! Indeed these (people) do not know me, but You know me.” [Source: Kitaab As-Samt’ of Ibn Abee Dunyaa.  Page: 272]
