3 جادّهُ فِى الأَمْرِ ذ , (S, L, K, *) inf. n. مُجَادَّةٌ, (L,) i. q. حَاقَّهٌ (S, L) or حَاقَقَهُ (K) [ He contended with him respecting a thing, each of them asserting his right therein: so accord. to explanations of حاقّهُ in the lexicons: but I think that the meaning intended here is, he acted seriously, or in earnest, with him in the affair; and this is confirmed by its being immediately added in the TA, after حاققه, “ and أَجَدَّ ” signifies “ حَقَّقَ, as above mentioned: ” see جَدَّفِى الأَمْرِ expl. by حَقَّقَ as contr. of هَزَلَ]. Also He exerted his full effort, or endeavour, or energy, with him in the affair. (So accord. to an explanation of the inf. n., مجادَة, in the KL.)
