بخس1 بَخَسَهُ, aor. ـَ inf. n. بَخْسٌ, He diminished it; lessened it; made it deficient, or defective: (S, A, Msb, K:) or he made it faulty. (Msb.) You say, بَخَسَ الكَيَّالُ [for بَخَسَ الكَيَّالُ الكَيْلَ The measurer made defective measure]. (A.) And of a just sale, لَا بَخْسَ فِيهِ وَ لَا شَطَطَ, (S,) or وَلَا شُطُوطَ, (T, TA,) [There is no deficiency in it nor excess.] And it is said in the Kur [lxxii. 13], فَلَا يَخَافُ بَخْسًا وَلَا رَهَقًا He shall not fear diminution of the reward of his actions, nor wrong, or injustice. (TA.) And in this sense, [as also in the next,] the verb is doubly trans. (Msb.) Yousay, بَخَسَهُ حَقَّهُ He diminished to him his right, or due; deprived him, or defrauded him, of a part of it. (S, A.) And it is said in the Kur [vii. 83 and xi. 86 and xxvi. 183], وَلَا تَبْخَسُوا النَّاسَ أَشْيَآءَهُمْ [And ye shall not diminish unto men their things]: (Msb:) or the verb in this instance has the signification next following. (TA.) b2:  He wronged him; acted wrongfully, or unjustly, towards him. (A, K.) A2:  بَخَسَ عَيْنَهُ: see بَخَصَ.6 تباخسوا They defrauded one another in a sale. (K.) بَخْسٌ Deficient; defective. (S.) It is said in the Kur [xii. 20], وَشَرَوْهُ بِثَمَنٍ بَخْسٍ And they sold him for a deficient, or defective, price: (S, * Msb, * TA:) or for a price less than was incumbent: or for an insufficient price: or for an unjust price; accord. to Zj; because the sale of a man that has been found is unlawful. (TA.) A2: Land that produces herbage without being [artificially] watered: (JK, S, K:) or land which is watered by the rain; because it has deficient watering: (Mgh:) pl. بُخُوسٌ. (JK, TA.) b2: Also, (TA, as from Ibn-Málik,) or ↓ بَخْسِىٌّ, [which is more probably the correct form,] a rel. n. from بَخْسٌ in the sense immediately preceding, explained in the T as signifying, (Mgh,) Seed-produce that is not irrigated with water from a spring or well or the like, but only by the rain. (Mgh, and TA from Ibn-Málik.) بَخْسِىٌّ: see بَخْسٌ.بَاخِسٌ Any one who acts wrongfully, or unjustly. (TA.) It is said in a prov., تَحْسِبُهَا حَمْقَآءَ وَ هِىَ بَاخِسٌ; (S, A, K;) so runs the prov.; but accord. to Th, (S,) you may also say بَاخِسَةٌ; (S, K;) i. e., [Thou thinkest her stupid,] but she is wrongful, or unjust: applied to him who feigns himself to be of weak understanding when he is crafty and cunning. (K, TA.) The origin of the prov. was this: a man of the Benu-l-' Ambar, of Temeem, mixed his property with that of a woman, coveting the possession of it, and thinking that she was stupid, and that she did not take care of her property nor know it: then he made a division with her, after he had mixed; but she was not content with the division until she took her property: she complained of him to those in authority, so that he released himself from her by giving her what she desired of the property: and the man was reproved for his conduct; it being said to him, “Thou cheatest a woman: is not this wrongful conduct (بَخْس)? ” whereupon he replied in the words above, which became a proverb. (Th, K, * TA.)
