It is implied in the K that the verb in this sense is ↓ قَسَطَ, of three letters [only, without teshdeed]. (TA.) You say, قسّط المَالَ بِيْنَهُمْ He distributed the property among them. (TA.) And قسّط الخَرَاجَ عَلَيْهِمْ He assigned the several portions which each one of them should pay of the [tax called] خراج: (TA:) or قسّط الخَرَاجَ, inf. n. as above, signifies he assessed, or apportioned, the خراج (Mgh, Msb) with equity and equality, (Mgh,) to be paid at certain times.

(TA.) It is said in the Kur, [iv. 3,] وَإِنْ خِفْتُمْ أَلَّا تُقْسِطُوا فِى اليَتَامَى [And if ye fear lest ye should not act equitably with respect to the orphans]: (Mgh:) or, accord. to one reading, ↓ تَقْسُطُوا, with damm to the س. (TA.) And you say also, أَقْسَطْتُ بَيْنَهُمْ [I acted equitably between them], and إِلَيْهِمْ [towards them]. (TA.) 5 تَقَسَّطُوا الشَّىْءِ بَيْنَهُمْ They divided the thing among themselves (Lth, S, * M [in which last بينهم is omitted] and O, L, K) equitably, (M, O,) or equitably and equally, (L,) or with equality.

(TA.) Sometimes it is used for performing the ablution termed وُضُوْء: and hence it is said in a trad., إِنَّ النِّسَآءَ مِنْ أَسْفَهِ السُّفَهَآءِإِلَّا صَاحِبَةَ القِسْطِ وَالسِّرَاجِ; (K;) the قِسْط being  here the vessel in which the وضوء is performed; (TA;) the meaning app. being, [Women are of the most lightwitted of the lightwitted,] except she who serves her husband, and assists him to perform the وضوء, [so I render تُوَضِّئُهُ,] and takes care of the vessel which he uses for that purpose, and stands at his head with the lamp: (K:) or who performs his affairs with respect to his وضوء and his lamp.
