The word(s) "neck" appears 13 time(s) in 13 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) When the yokes (shall be) round their necks, and the chains; they shall be dragged along-

(12) Therefore, when ye meet the Unbelievers (in fight), smite at their necks; At length, when ye have thoroughly subdued them, bind a bond firmly (on them): thereafter (is the time for) either generosity or ransom: Until the war lays down its burdens. Thus (are ye commanded): but if it had been Allah's Will, He could certainly have exacted retribution from them (Himself); but (He lets you fight) in order to test you, some with others. But those who are slain in the Way of Allah,- He will never let their deeds be lost.

(13) A twisted rope of palm-leaf fibre round her (own) neck!
