And thus We have made you a middle community (probably with respect to location and time) that you may be witnesses (by keeping an eye) on mankind and the messenger may be a witness (by keeping an eye) on you. And We had appointed the Qiblah, towards which you used to (turn earlier), only to know (distinguish) one who follows the messenger, from one who turns away on his heels. And that was a great (test) except for those whom Allah had guided, and Allah will not waste your belief, Allah is certainly full of pity for human beings, Merciful.
