Mukhtasar Sahih Bukhari — Hadith 1557

Sayyiduna Bara’ (may Allah be pleased with him) reports that the Prophet Muhammad (peace and blessings be upon him) said: “None but a believer will love the Ansar, and none but a hypocrite will hate them. So whoever loves the Ansar, Allah will love him, and whoever hates the Ansar, Allah will hate him.”
