Quran 2:144 — The Heifer (Al-Baqarah)

We have seen you turning your face about the sky (searching for the right direction). We now assign a Qiblah that is pleasing to you. Henceforth, you shall turn your face towards the Sacred Masjid. Wherever you may be, all of you shall turn your faces towards it. Those who received the previous scripture know that this is the truth from their Lord. GOD is never unaware of anything they do.

[2:143] We thus made you an impartial community, that you may serve as witnesses among the people, and the messenger serves as a witness among you. We changed the direction of your original Qiblah only to distinguish those among you who readily follow the messenger from those who would turn back on their heels. It was a difficult test, but not for those who are guided by GOD. GOD never puts your worship to waste. GOD is Compassionate towards the people, Most Merciful.

[2:145] Even if you show the followers of the scripture every kind of miracle, they will not follow your Qiblah. Nor shall you follow their Qiblah. They do not even follow each others' Qiblah. If you acquiesce to their wishes, after the knowledge that has come to you, you will belong with the transgressors.
