سَبًا

Also A tribe of El-Yemen; regarded as a حَىّ, perfectly decl.; and regarded as a قَبِيلَة, [and therefore a feminine proper name,] imperfectly decl. [and written سَبَا]: (M, TA:) or, as is said in the Msb, it is the name of a town, or province, in El-Yemen; masculine, and therefore perfectly decl.; and feminine, and therefore imperfectly decl.; called by the name of its builder: (TA:) [hence,] one says, ذَهَبُوا أَيْدِى سَبَا and أَيَادِى سَبَا, [making the last word to be without tenween either as a feminine proper name or because of pausing after it,] i. e. They went away scattered, or dispersed: (S, M, K:) J says, (TA,) they are two nouns made one, like مَعْدِى كَرِبَ, perfectly decl. because not occurring otherwise than as a denotative of state, [and therefore indeterminate,] whether you make the former to be a prefixed noun governing the latter in the gen. case, or do not so. (S, TA. [See also article سبأ.])

In a verse of 'Alkameh Ibn-'Abadeh, the phrase بِسَبَا الكَتَّانِ is used for بِسَبَايءِبِ الكَتَّانِ. (M in article سب: see سِبٌّ.)
