The word(s) "prosecution" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) O ye who believe! Retaliation is prescribed for you in the matter of the murdered; the freeman for the freeman, and the slave for the slave, and the female for the female. And for him who is forgiven somewhat by his (injured) brother, prosecution according to usage and payment unto him in kindness. This is an alleviation and a mercy from your Lord. He who transgresseth after this will have a painful doom.

(2) He it is Who hath placed you as viceroys of the earth and hath exalted some of you in rank above others, that He may try you by (the test of) that which He hath given you. Lo! Thy Lord is swift in prosecution, and Lo! He verily is Forgiving, Merciful.

(3) And (remember) when thy Lord proclaimed that He would raise against them till the Day of Resurrection those who would lay on them a cruel torment. Lo! verily thy Lord is swift in prosecution and lo! verily He is Forgiving, Merciful.
