The word(s) "strive" appears 39 time(s) in 35 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) For those whose hopes are in the meeting with Allah (in the Hereafter, let them strive); for the term (appointed) by Allah is surely coming and He hears and knows (all things).

(22) And if any strive (with might and main), they do so for their own souls: for Allah is free of all needs from all creation.

(23) We have enjoined on man kindness to parents: but if they (either of them) strive (to force) thee to join with Me (in worship) anything of which thou hast no knowledge, obey them not. Ye have (all) to return to me, and I will tell you (the truth) of all that ye did.

(24) And those who strive in Our (cause),- We will certainly guide them to our Paths: For verily Allah is with those who do right.

(25) "But if they strive to make thee join in worship with Me things of which thou hast no knowledge, obey them not; yet bear them company in this life with justice (and consideration), and follow the way of those who turn to me (in love): in the end the return of you all is to Me, and I will tell you the truth (and meaning) of all that ye did."

(26) But those who strive against Our Signs, to frustrate them,- for such will be a Penalty,- a Punishment most humiliating.

(27) Those who strive against Our Signs, to frustrate them, will be given over into Punishment.

(28) For the like of this let all strive, who wish to strive.

(29) And We shall try you until We test those among you who strive their utmost and persevere in patience; and We shall try your reported (mettle).

(30) Only those are Believers who have believed in Allah and His Messenger, and have never since doubted, but have striven with their belongings and their persons in the Cause of Allah: Such are the sincere ones.
