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

2:49And recall that We delivered you from the people of Pharaoh. They inflicted on you terrible persecution, killing your sons and sparing your women. Therein was a tremendous trial from your Lord.

2:85But here you are, killing your own, and expelling a group of your own from their homes—conspiring against them in wrongdoing and hostility. And if they come to you as captives, you ransom them, although it was forbidden to you. Is it that you believe in part of the Scripture, and disbelieve in part? What is the reward for those among you who do that but humiliation in this life? And on the Day of Resurrection, they will be assigned to the most severe torment. God is not unaware of what you do.

2:87We gave Moses the Scripture, and sent a succession of messengers after him. And We gave Jesus son of Mary the clear proofs, and We supported him with the Holy Spirit. Is it that whenever a messenger comes to you with anything your souls do not desire, you grew arrogant, calling some impostors, and killing others?

2:217They ask you about fighting during the Holy Month. Say, “Fighting during it is deplorable; but to bar others from God’s path, and to disbelieve in Him, and to prevent access to the Holy Mosque, and to expel its people from it, are more deplorable with God. And persecution is more serious than killing. They will not cease to fight you until they turn you back from your religion, if they can. Whoever among you turns back from his religion, and dies a disbeliever—those are they whose works will come to nothing, in this life, and in the Hereafter. Those are the inmates of the Fire, abiding in it forever.
