ضلع

مُضْطَلِعٌ ذ is from الضَّلَاعَةُ [inf. n. of ضَلُعَ]: so in the saying, فُلَانٌ مُضْطَلِعٌ بِهٰذَا الأَمْرِ i. e. Such a one is possessed of strength, or power, sufficient for this affair: so says ISk: and he adds that one should not say مُطَّلِعٌ: Aboo-Nasr Ahmad Ibn- Hátim says, one says هُوَ مُضْطَلِعٌ بِهٰذَا الأَمْرِ and مُطَّلِعٌ له [also]; الاِضْطِلَاعُ being from الضَّلَاعَةُ meaning القُوَّةُ; and الاِطِّلَاعُ being from العُلُوُّ, from the saying اِطَّلَعْتُ الثَّنِيَّةَ meaning عَلَوْتُهَا [I ascended upon the mountain, or mountain-road, termed ثَنِيَّة]; i. e. he is one who has ascendancy with respect to this affair, who is master of it: (S, O, TA:) Lth expressly allows مُطَّلِعٌ for مُضْطَلِعٌ by the incorporation of the ض into the [letter that is originally] ت, so that the two together become ط with teshdeed. (TA.) And لِهٰذَا الأَمْرِ ↓ هُوَ مُضْلِعٌ means the same as مُضْطَلِعٌ as first expl. above, i. e. He is possessed of strength, or power, sufficient for this affair. (O, K. [In both, in this instance, لِهٰذَا, not بِهٰذَا.]) In the phrase اـِذَا كَانَ مُضْطَلِعًا عَلَى حَقِّهِ [ If he be possessed of power, or ability, to obtain his right, or due ], it seems that مضطلعا is made trans. by means of على because made to imply the meaning of قَادِرًا or مُقْتَدِرًا. (Mgh.) ↓ مُسْتَضْلِعٌ, likewise, signifies Having strength, or power. (TA.)
