Read the full account
After the Trench, later sira dates the killing of Banu Qurayza's fighting men and the enslavement of others under a judgment Muhammad accepted. It is a completed lethal sentence, not a parable. Muhammad's documented role is: He accepted Sa'd ibn Mu'adh's judgment and the sentence was carried out in the received file. He did not sit as a modern court of appeal.
Context

Driver justice-judicial-independence-erosion is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
