نَجِسٌ
1.
and
نَجَسٌ (S, A, O, Msb, K) and
نَجُسٌ and
نَجْسٌ and
نِجْسٌ (A, O, K) Unclean, dirty, filthy, or impure: (A, Msb, K:) the last of these is only used when the word is preceded or followed by رِجْسٌ: (ISd:) or only when it is preceded by رِجْسٌ: (Fr, S, * and Har in the Durrat-el-Ghowwás:) but this remark correctly applies only to the greater number of instances: (M, F:) the second of the above five forms is a verbal noun used as an epithet; (A, Msb;) and is [therefore] used as singular and dual. and plural and masculine and feminine, without variation: (TA:) [and the first and last are also used as pls., as will be seen below; but when so used, I suppose قَوْمٌ or some other coll. gen. n. to be understood:] the plural [of every one of the other forms] is أَنْجَاسٌ (A, Msb, TA) and [of the fourth and fifth, and perhaps of the first and third also, though I do not remember similar instances,] نِجْسَةٌ. (TA.) [See also نَجَاسَةٌ, below.] نَجِسٌ and
نَجْسٌ [&c.], applied to a man, signify Unclean, &c., [both properly and tropically]. (TA.) [The two following examples are said in the A to be tropical.] النَّاسُ أَجْنَاسٌ وَأَكْثَرُهُمْ أَنْجَاسٌ (tropical:) [Men are of several kinds, and most of them are unclean.] (A, TA.) And إِنَّمَا الْمُشْرِكُونَ نَجَسٌ (tropical:) [Verily the associaters of others with God are but unclean], said in the Qur'an, 9:28,] (S, A, TA,) or نَجِسٌ, or
نِجْسٌ, according to certain readers. (TA.)
