Hadith 485:2
Ziyad ibn al-Rabi' narrated to us, 'Abbad ibn Kathir al-Shami, from the people of Palestine, narrated to us, from a woman among them who is called Fusaylah, she said: I heard my father saying: I asked the Messenger of Allah, peace and blessings of Allah be upon him, and I said: O Messenger of Allah, is it from tribalism (asabiyyah) that a man loves his people? He said: "No, but it is from tribalism that a man aids his people in injustice."
حدثنا زياد بن الربيع، حدثنا عباد بن كثير الشامي، من أهل فلسطين، عن امرأة منهم يقال لها فسيلة، قالت: سمعت أبي، يقول: سألت رسول الله صلى الله عليه وسلم فقلت: يا رسول الله، أمن العصبية أن يحب الرجل قومه؟ قال: " لا، ولكن من العصبية أن يعين الرجل قومه على الظلم "
