Hazrat Hakam bin Mina (may Allah have mercy on him) narrates that Hazrat Yazid bin Jariyah (may Allah be pleased with him) said: I was sitting among a group of the Ansar when Hazrat Muawiyah (may Allah be pleased with him) passed by us. He asked the people about what they were discussing. The people replied: We are talking about the Ansar. Upon this, Hazrat Muawiyah (may Allah be pleased with him) said: Shall I not narrate to you a hadith which I myself heard from the Messenger of Allah (peace and blessings be upon him)? The people said: O Commander of the Faithful, why not! Certainly! He (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: Whoever loves the Ansar, Allah will also love him. And whoever harbors enmity against the Ansar, Allah will also harbor enmity against him.
