Al-Baqarah 2:143

Wakathalika jaAAalnakumommatan wasatan litakoonoo shuhadaa AAala annasiwayakoona arrasoolu AAalaykum shaheedan wamajaAAalna alqiblata allatee kunta AAalayha illalinaAAlama man yattabiAAu arrasoola mimman yanqalibu AAalaAAaqibayhi wa-in kanat lakabeeratan illa AAalaallatheena hada Allahu wama kanaAllahu liyudeeAAa eemanakum inna Allahabinnasi laraoofun raheem

And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels. And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful.

In the same way We made you a moderate Ummah (community), so that you should be witnesses over the people, and the Messenger a witness to you.And We did not prescribe the Qiblah which you used to observe except to know the one who follows the Messenger as distinct from the one who turns on his heels. It was burdensome indeed, but not on those whom Allah guided. Allah will not allow your faith go to waste. Certainly Allah is very kind, very merciful to the people.
