do one's utmost

Is that discouragement, to look one's future steadily in the face, and do one's utmost to avert misfortune?

His Life is not the kind of thing one would like to put into the hands of young people; rather, one would do one’s utmost to keep it from their knowledge, as a red flag of adventure and disintegrating influence in life.

It means, as used by the classical poets as well as by the Koran, to do one's utmost; to labour; to toil; to exert one's-self or his power, efforts, endeavours, or ability; to employ one's-self vigorously, diligently, studiously, sedulously, earnestly, or with energy; to be diligent or studious, to take pains or extraordinary pains.

I believe that I have clearly shown by means of a careful comparison between the translators and commentators and the original passages in the Koran, that the word Jahd or Jihád in the classical Arabic and as used in the Koran does not mean waging war or fighting, but only to do one's utmost and to exert, labour or toil.

And Ibn Ábidin Shámi, in his annotation on the above work, says: "The infinitive noun of Jáhada means to do one's utmost, and that it is general, and includes any person who supports all that is reasonable and forbids what is wrong."
