Sayyiduna Jarir bin Abdullah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "The Muhajirun and the Ansar are friends of each other in this world and the Hereafter. The Tulaqa from the Quraysh and the Utaqa from the Thaqif are friends of each other in this world and the Hereafter."
