Musannaf Ibn Abi Shayba 36:562

Ghundar narrated to us, from Shu'bah, from Sa'd ibn Ibrahim, who said: I heard 'Ubayd Allah ibn Abi Rafi' say: I saw 'Ali when they crowded around him until they caused his foot to bleed. He said: "O Allah, I have disliked them and they have disliked me, so relieve me of them and relieve them of me."
