And so We have made you a median nation, in order that you will be a witness above the people, and that the Messenger be a witness above you. We did not change the direction that you were facing except that We might know who followed the Messenger from him who turned on both his heels. Though it was a hardship except for those whom Allah has guided. But Allah would never waste your faith. Indeed, Allah is Gentle with people, the Most Merciful.
