Thus have we made you a central people, that ye may be witnesses in regard to mankind, and that the apostle may be a witness in regard to you. We appointed the kebla which thou formerly hadst, only that we might know him who followeth the apostle, from him who turneth on his heels: The change is a difficulty, but not to those whom God hath guided. But God will not let your faith be fruitless; for unto man is God Merciful, Gracious.
