Quran 2:141 — The Heifer (Al-Baqarah)

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.

[2:140] Do you say that Abraham, Ismail, Isaac, Jacob, and the Patriarchs were Jewish or Christian? Say, "Do you know better than GOD? Who is more evil than one who conceals a testimony he has learned from GOD? GOD is never unaware of anything you do."

[2:142] 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."
