Musannaf Ibn Abi Shayba 27:715

Shababa narrated to us, he said: Shu'bah narrated to us, he said: 'Adi ibn Thabit narrated to us, from Al-Bara' ibn 'Azib, he said: The Messenger of Allah (may Allah bless him and grant him peace) said: "None loves the Ansar except a believer, and none hates them except a hypocrite. Whoever loves them, Allah loves him, and whoever hates them, Allah hates him."
