Narrated 'Ali:
Sufyan was asked whether (the Verse): 'Take not My enemies and your enemies...'
was revealed in connection with Hatib. Sufyan replied, "This occurs only in the narration of the people. I memorized the Hadith from 'Amr, not overlooking even a single letter thereof, and I do not know of anybody who remembered it by heart other than myself."
