جهد

3 جِهَادٌ جهاد , inf. n. of جاهد, properly signifies The using, or exerting, one's utmost power, efforts, endeavours, or ability, in contending with an object of disapprobation; and this is of three kinds, namely, a visible enemy, the devil, and one's self; all of which are included in the term as used in the Kur xxii. 77. (Er-Rághib, TA.) See also 1, first sentence. You say, جاهد العَدُوَّ, (JK, A, Mgh,) inf. n. as above (JK, Mgh, K) and مُجَاهَدَةٌ, (JK, K,) He fought with the enemy: (K:) or he encountered the enemy, imposing upon himself difficulty or distress or fatigue, or exerting his power or efforts or endeavours or ability, [or the utmost thereof, ] to repel him, his enemy doing the like: and hence جاهد came to be used by the Muslims to signify generally he fought, warred, or waged war, against unbelievers and the like. (Mgh.) You say also, جاهد فِى سَبِيلِ ا@للّٰهِ, inf. n. جِهَادٌ (S, Msb) and مُجَاهَدَةٌ, (S,) [ He fought, &c., in the way of God; i. e., in the cause of religion. ]
