The word(s) "striven" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) Verily, those who have believed, and those who have emigrated (for Allah's Religion) and have striven hard in the Way of Allah, all these hope for Allah's Mercy. And Allah is Oft-Forgiving, Most-Merciful.

(2) Do you think that you shall be left alone while Allah has not yet tested those among you who have striven hard and fought and have not taken Walijah [(Bitanah - helpers, advisors and consultants from disbelievers, pagans.) giving openly to them their secrets] besides Allah, and His Messenger, and the believers. Allah is Well-Acquainted with what you do.
