It is narrated from Sayyiduna Abu Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "The one who should lead the people in prayer is the one among them who is the best reciter of the Qur'an and has the most knowledge of recitation. If they are equal in recitation, then the one who migrated first should lead. If they are also equal in migration, then the oldest among them should lead. No one should lead in another person's house or authority, and likewise, no one should sit in a place of honor in someone else's house except with his permission."
