Quran 2:72 — The Heifer (Al-Baqarah)

You had killed a person, then disputed among yourselves. GOD was to expose what you tried to conceal.

[2:71] He said, "He says that she is a heifer that was never humiliated in plowing the land or watering the crops; free from any blemish." They said, "Now you have brought the truth." They finally sacrificed her, after this lengthy reluctance.

[2:73] We said, "Strike (the victim) with part (of the heifer)." That is when GOD brought the victim back to life, and showed you His signs, that you may understand.
