عَرْفٌ

1.
An odour, whether fragrant or fetid, (S, O, K, TA,) in most instances the former, (K, TA,) as when it is used in relation to Paradise: (TA:) and عَرْفَةٌ signifies [the same, i. e.] رِيحٌ (K, TK) and رَايءِحَةٌ. (TK.) One says, ما أَطْيَبَ عَرْفَهُ [How fragrant is its odour!]. (S, O.) And لَا يَعْجِزُ مَسْكُ السَّوْءِ عَنْ عَرْفِ السَّوْءِ [The bad hide will not lack the fetid odour]; (S, O, K;) a prov.; (S, O;) applied to the low, ignoble, mean, or sordid, who will not cease from his evil doing; he being likened to the hide that is not fit for being tanned; (O, K;) wherefore it is cast aside, and becomes fetid. (O.) And some read, in the Qur'an, 77:1, وَالْمُرْسَلَاتِ عَرْفًا, [as meaning By the winds that are sent forth with fragrance,] instead of عُرْفًا. (TA.)
2.
Also A certain plant: or the ثُمَام [or panic grass]: (K:) or a certain plant, not of the [kind called] حَمْض, nor of the [kind called] عِضَاه; (Ibn-'Abbád, O, L, K;) of the [kind called] ثُمَام. (Ibn-'Abbád, O, L.)
