The word(s) "strove" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Pickthal translation.

(1) Lo! those who believed and left their homes and strove with their wealth and their lives for the cause of Allah, and those who took them in and helped them: these are protecting friends one of another. And those who believed but did not leave their homes, ye have no duty to protect them till they leave their homes; but if they seek help from you in the matter of religion then it is your duty to help (them) except against a folk between whom and you there is a treaty. Allah is Seer of what ye do.

(2) Those who believed and left their homes and strove for the cause of Allah, and those who took them in and helped them - these are the believers in truth. For them is pardon, and bountiful provision.

(3) And those who afterwards believed and left their homes and strove along with you, they are of you; and those who are akin are nearer one to another in the ordinance of Allah. Lo! Allah is Knower of all things.

(4) And they indeed strove hard to beguile thee (Muhammad) away from that wherewith We have inspired thee, that thou shouldst invent other than it against Us; and then would they have accepted thee as a friend.
