The word(s) "achievement" appears 19 time(s) in 19 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And keep them from evil deeds, and whom Thou keepest from evil deeds this day, indeed Thou hast mercy on him, and that is the mighty achievement.

(12) A grace from your Lord; this is the great achievement.

(13) Then as to those who believed and did good, their Lord will make them enter into His mercy; that is the manifest achievement.

(14) That He may cause the believing men and the believing women to enter gardens beneath which rivers flow to abide therein and remove from them their evil; and that is a grand achievement with Allah

(15) On that day you will see the faithful men and the faithful women-- their light running before them and on their right hand-- good news for you today: gardens beneath which rivers flow, to abide therein, that is the grand achievement.

(16) He will forgive you your faults and cause you to enter into gardens, beneath which rivers flow, and goodly dwellings in gardens of perpetuity; that is the mighty achievement;

(17) On the day that He will gather you for the day of gathering, that is the day of loss and gain; and whoever believes in Allah and does good, He will remove from him his evil and cause him to enter gardens beneath which rivers flow, to abide therein forever; that is the great achievement.

(18) Surely for those who guard (against evil) is achievement,

(19) Surely (as for) those who believe and do good, they shall have gardens beneath which rivers flow, that is the great achievement.
