It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The Hour will not be established until you become (once again) people who fight one another, and until a man goes to a Nabataean woman and marries her for the sake of his livelihood, and abandons his paternal cousin, not even looking at her."
