It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, everything has a nisbah (a description or lineage), and the nisbah of Allah Almighty is 'Qul huwa Allahu ahad' (Say: He is Allah, the One)."
This hadith is not narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) except with this chain, and Abd al-Rahman bin Nafi' is alone in narrating it.
