Musannaf Ibn Abi Shayba 27:426

Abu Mu'awiyah and Waki' narrated to us, from al-A'mash, from 'Adi ibn Thabit, from Zirr ibn Hubaysh, from 'Ali ibn Abi Talib, who said: "By the One who split the seed and created the soul, it is a covenant of the unlettered Prophet (ﷺ) to me that none shall love me except a believer, and none shall hate me except a hypocrite."
