The word(s) "killing" appears 19 time(s) in 18 verse(s) in Quran in Mohsin Khan translation.

(1) And (remember) when We delivered you from Fir'aun's (Pharaoh) people, who were afflicting you with a horrible torment, killing your sons and sparing your women, and therein was a mighty trial from your Lord.

(2) And kill them wherever you find them, and turn them out from where they have turned you out. And Al-Fitnah is worse than killing. And fight not with them at Al-Masjid-Al-Haram (the sanctuary at Makkah), unless they (first) fight you there. But if they attack you, then kill them. Such is the recompense of the disbelievers.

(3) They ask you concerning fighting in the Sacred Months (i.e. 1st, 7th, 11th and 12th months of the Islamic calendar). Say "Fighting therein is a great (transgression) but a greater (transgression) with Allah is to prevent mankind from following the Way of Allah, to disbelieve in Him, to prevent access to Al-Masjid-Al-Haram (at Makkah), and to drive out its inhabitants, and Al-Fitnah is worse than killing. And they will never cease fighting you until they turn you back from your religion (Islamic Monotheism) if they can. And whosoever of you turns back from his religion and dies as a disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will be the dwellers of the Fire. They will abide therein forever."

(4) If a wound (and killing) has touched you, be sure a similar wound (and killing) has touched the others. And so are the days (good and not so good), We give to men by turns, that Allah may test those who believe, and that He may take martyrs from among you. And Allah likes not the Zalimun (polytheists and wrong-doers).

(5) And Allah did indeed fulfil His Promise to you when you were killing them (your enemy) with His Permission; until (the moment) you lost your courage and fell to disputing about the order, and disobeyed after He showed you (of the booty) which you love. Among you are some that desire this world and some that desire the Hereafter. Then He made you flee from them (your enemy), that He might test you. But surely, He forgave you, and Allah is Most Gracious to the believers.

(6) Indeed, Allah has heard the statement of those (Jews) who say: "Truly, Allah is poor and we are rich!" We shall record what they have said and their killing of the Prophets unjustly, and We shall say: "Taste you the torment of the burning (Fire)."

(7) Because of their breaking the covenant, and of their rejecting the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, and of their killing the Prophets unjustly, and of their saying: "Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)" - nay, Allah has set a seal upon their hearts because of their disbelief, so they believe not but a little.

(8) And so to many of the Mushrikun (polytheists - see V.2:105) their (Allah's so-called) "partners" have made fair-seeming the killing of their children, in order to lead them to their own destruction and cause confusion in their religion. And if Allah had willed, they would not have done so. So leave them alone with their fabrications.

(9) And (remember) when We rescued you from Fir'aun's (Pharaoh) people, who were afflicting you with the worst torment, killing your sons and letting your women live. And in that was a great trial from your Lord.

(10) And kill not your children for fear of poverty. We shall provide for them as well as for you. Surely, the killing of them is a great sin.
