Musnad Ahmad 457:30

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Isma'il ibn Raja', he said: I heard Aws ibn Dam'aj saying: I heard Abu Mas'ud saying: The Messenger of Allah, may Allah bless him and grant him peace, said to us: "The people shall be led in prayer by the one among them who is most proficient in the Book of Allah, the Exalted, and the earliest of them in recitation. If their recitation is equal, then the earliest of them in migration shall lead them. If they are equal in migration, then the oldest of them in age shall lead them. And a man shall not lead another in his household, nor in his place of authority, and he shall not sit on his seat of honor in his house, unless he gives him permission or by his leave."
