The one of you who is most versed in the Books of Allah should act as imam for the people; and the one who is the earliest of them in reciting (the Qur'an); if they are equally versed in reciting it, then the earliest of them to emigrate (to Medina); if they emigrated at the same time, then the oldest of them. No man must lead another in prayer in his house (i.e. in the house of a latter) or where the latter has authority, or sit in his place of honor without his permission. Shu'bah said: I asked Isma'il: what is the meaning of his place of honor? He replied: his throne.
