Sayyiduna Jabir (may Allah be pleased with him) narrates that a Muhajir man struck an Ansari man on his back with his hand or foot (and because of this a fight broke out). The Ansari called out: "O Ansar!" The Muhajir called out: "O Muhajir!" Upon hearing this, the Messenger of Allah (peace and blessings be upon him) said: Beware! What is the reason for calling out with the call of ignorance? Leave such mischiefs; they are blameworthy.
