Thus have We made you a middle (or justly balanced) nation, to be witnesses against men, and that the Apostle may be a witness against you. We have not appointed the Qiblah (direction, focus, goal) which you were used to, save that We might know (test) who follows the Apostle from him who turns upon his heels, although it is a great thing save for those whom Allah does guide. But Allah will not waste your faith, for verily, Allah is to all people full of Kindness, Most Merciful.
