The word(s) "successful" appears 37 time(s) in 37 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) These are on a guidance from their Lord, and these are they who are successful:

(32) You shall not find a people who believe in Allah and the latter day befriending those who act in opposition to Allah and His Apostle, even though they were their (own) fathers, or their sons, or their brothers, or their kinsfolk; these are they into whose hearts He has impressed faith, and whom He has strengthened with an inspiration from Him: and He will cause them to enter gardens beneath which rivers flow, abiding therein; Allah is well-pleased with them and they are well-pleased with Him these are Allah's party: now surely the party of Allah are the successful ones.

(33) And those who made their abode in the city and in the faith before them love those who have fled to them, and do not find in their hearts a need of what they are given, and prefer (them) before themselves though poverty may afflict them, and whoever is preserved from the niggardliness of his soul, these it is that are the successful ones.

(34) But when the prayer is ended, then disperse abroad in the land and seek of Allah's grace, and remember Allah much, that you may be successful.

(35) Therefore be careful of (your duty to) Allah as much as you can, and hear and obey and spend, it is better for your souls; and whoever is saved from the greediness of his soul, these it is that are the successful.

(36) He indeed shall be successful who purifies himself,

(37) He will indeed be successful who purifies it,
