He said, "He says it is a heifer which was never subjugated to plough the land, or water the crops, free from any blemish." They said, "Now you have come with the truth." They slaughtered it, though they had nearly not done so.

You had murdered a person, and then disputed in the matter; God was to bring out what you were keeping secret.

We said, "Strike him with its parts." It is thus that God brings the dead to life, and He shows you His signs that you may reason.

Despite this, your hearts hardened; like rocks. Or even harder, since some rocks allow rivers to gush out, others crack and release water, and some rocks fall down out of reverence for God. God is never unaware of what you do.

Did you expect that they would acknowledge for you, when a group of them had heard God's words then altered them knowingly after what they had reasoned?
