The word(s) "ransom" appears 13 time(s) in 13 verse(s) in Quran in Muhammad Pickthal translation.

(11) Now when ye meet in battle those who disbelieve, then it is smiting of the necks until, when ye have routed them, then making fast of bonds; and afterward either grace or ransom till the war lay down its burdens. That (is the ordinance). And if Allah willed He could have punished them (without you) but (thus it is ordained) that He may try some of you by means of others. And those who are slain in the way of Allah, He rendereth not their actions vain.

(12) So this day no ransom can be taken from you nor from those who disbelieved. Your home is the Fire; that is your patron, and a hapless journey's end.

(13) Though they will be given sight of them. The guilty man will long to be able to ransom himself from the punishment of that day at the price of his children
