Khalaf Bin Tameem (rahimahullaah) said: I saw Ath-Thawree (i.e. Sufyaan) at Makkah and many (people gathered around him or came to him); so he said: To Allaah do we belong, I fear that Allaah has made this Ummah to be lost when the people are in need of the likes of me. [Siyar 7/275]

And whenever he (rahimahullaah) was told that he has been seen in a dream, he would say: I know myself more than those who see me in a dream. [Siyar 7/252]
