It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever I am his mawla (patron), Ali is (also) his mawla. O Allah, befriend whoever befriends him, and be hostile to whoever is hostile to him."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Ikrimah narrated this hadith from Idris, and al-Nufayli is alone in narrating it."
