killed
in Edition Clear Qur'an by Talal Itani / Al-Baqara (The Cow)

2:61And recall when you said, “O Moses, we cannot endure one kind of food, so call to your Lord to produce for us of what the earth grows: of its herbs, and its cucumbers, and its garlic, and its lentils, and its onions.” He said, “Would you substitute worse for better? Go down to Egypt, where you will have what you asked for.” They were struck with humiliation and poverty, and incurred wrath from God. That was because they rejected God’s revelations and wrongfully killed the prophets. That was because they disobeyed and transgressed.

2:72And recall when you killed a person, and disputed in the matter; but God was to expose what you were hiding.

2:154And do not say of those who are killed in the cause of God, “Dead.” Rather, they are alive, but you do not perceive.

2:251And they defeated them by God’s leave, and David killed Goliath, and God gave him sovereignty and wisdom, and taught him as He willed. Were it not for God restraining the people, some by means of others, the earth would have gone to ruin. But God is gracious towards mankind.
