Musnad Ahmad 31:430

Hajjaj narrated to us, Shu'bah informed us, and Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from 'Amr ibn Dinar, from Sulayman al-Yashkuri, from Abu Sa'id al-Khudri, that he said regarding the "wahm" (delusion/misconception): "He seeks/intends." A man said to him: "From the Prophet, may Allah bless him and grant him peace?" He said: "As far as I know."
