عصم

أَعْصَمُ ذ A gazelle, and a mountain-goat, having in his arms, (As, T, S, K,) or in one of them, (AO, S, M, K,) a whiteness, (S, K,) the rest of him being red or black: (K:) or a goat white in the fore legs, or in the fore leg: (Az, TA:) fem. عَصْمَاآءُ: (S, K:) and pl. عُصْمٌ. (S.) ― -b2- And A horse white in the fore leg: (As, TA:) or having a whiteness in one of his fore legs, above the pastern: (ISh, TA:) or having a whiteness in his fore shanks: (Ham p. 18:) or having a whiteness in one of his fore legs, (S, TA,) but not in his hind legs, (TA,) little or much; in which case he is termed أَعْصَمُ اليُمْنَى or اليُسْرَى [ white in respect of the right fore leg or of the left ]: when the whiteness is in both of his fore legs, he is termed أَعْصَمُ اليَدَيْنِ [ white in respect of the two fore legs ]; unless having a blaze in his face, in which case he is termed مُحَجَّلٌ, not أَعْصَمُ; (S, TA;) though a blaze in his face does not cause him to be termed مُحَجَّلٌ when the whiteness is in one fore leg. (S.) ― -b3- And A crow having a white feather in its wing; (S, K; [in some copies of the K, in its two wings; ]) i. e., in one of its wings: (TA:) because the wing of the bird corresponds to the fore leg [of the beast]: (S, TA:) or white in the wings: (ISh, IAth, TA:) or white in the legs: (TA:) or red (أَحْمَر) in the legs and beak; (Az, K, TA;) and this is said by Az to be the correct explanation; [but] he adds that the Arabs term بَيَاض [i. e. whiteness] حَمْرَة [which properly signifies redness], saying of a woman of white complexion that she is حَمْرَاآء: [so that by the last of the foregoing explanations of أَعْصَمُ applied to a crow is app. meant white in the legs and beak: ] the Prophet is said to have explained this epithet, thus applied, as meaning of which one of the legs is white: (TA:) some say that الغُرَابُ الأَعْصَمُ is like الأَبْلَقُ العَقُوقُ and بَيْضُ الأَنوقِ, applied to anything that is rarely found: (S, TA:) it occurs in a number of trads.; and a righteous woman is likened thereto.
