Quran 2:142 — The Heifer (Al-Baqarah)

The fools among the people would say, "Why did they change the direction of their Qiblah?" Say, "To GOD belongs the east and the west; He guides whoever wills in a straight path."

[2:141] That was a community from the past. They are responsible for what they earned, and you are responsible for what you earned. You are not answerable for anything they did.

[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.
