Abu Mijlaz Lahiq bin Humayd relates that it is narrated from Sayyiduna Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is killed under a banner of blindness, fighting for tribal partisanship and becoming angry for partisanship, his death is a death of Jahiliyyah (pre-Islamic ignorance)."
