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

(11) Go ye forth, (whether equipped) lightly or heavily, and strive and struggle, with your goods and your persons, in the cause of Allah. That is best for you, if ye (but) knew.

(12) O Prophet! strive hard against the unbelievers and the Hypocrites, and be firm against them. Their abode is Hell,- an evil refuge indeed.

(13) Those who were left behind (in the Tabuk expedition) rejoiced in their inaction behind the back of the Messenger of Allah: they hated to strive and fight, with their goods and their persons, in the cause of Allah: they said, "Go not forth in the heat." Say, "The fire of Hell is fiercer in heat." If only they could understand!

(14) When a Sura comes down, enjoining them to believe in Allah and to strive and fight along with His Messenger, those with wealth and influence among them ask thee for exemption, and say: "Leave us (behind): we would be with those who sit (at home)."

(15) But the Messenger, and those who believe with him, strive and fight with their wealth and their persons: for them are (all) good things: and it is they who will prosper.

(16) But verily thy Lord,- to those who leave their homes after trials and persecutions,- and who thereafter strive and fight for the faith and patiently persevere,- Thy Lord, after all this is oft-forgiving, Most Merciful.

(17) Those who do wish for the (things of) the Hereafter, and strive therefor with all due striving, and have Faith,- they are the ones whose striving is acceptable (to Allah).

(18) "But those who strive against Our Signs, to frustrate them,- they will be Companions of the Fire."

(19) And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the cult of your father Abraham. It is He Who has named you Muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah! He is your Protector - the Best to protect and the Best to help!

(20) Therefore listen not to the Unbelievers, but strive against them with the utmost strenuousness, with the (Qur'an).
