Narrated Shu'bah: from 'Adi bin Thabit, from Al-Bara bin 'Azib, that he heard the Prophet (ﷺ), or - he said: "The Prophet (ﷺ) said, about the Ansar: 'No one loves them except a believer, and no one hates them except a hypocrite. Whoever loves them, then Allah loves him, and whoever hates them then Allah hates him.'" So we said to him: "Did you hear this from Al-Bara?" He said: "He narrated it to me."
