(TA.) You say, نُكِسَ السَّهْمُ فِى الكِنَانَةِ The arrow was turned, or put, upside down in the quiver. (TA.) And it is said in the Kur, [xxxvi. 68,] وَمَنْ نُعَمِّرْهُ نَنْكُسْهُ فِى الخَلْقِ, or, accord. to the reading of 'Ásim and Hamzeh, ↓ نُنَكِّسْهُ; meaning, And him whom We cause to live long, We cause him to become in a state the reverse of that in which he was, in constitution; so that after strength, he becomes reduced to weakness; and after youthfulness, to extreme old age. (TA.) b2:  نَكَسْتُ فُلَانًا فِى ذٰلِكَ الأَمْرِ (assumed tropical:)  I  made such a one to enter again into that affair, or state, after he had got out of it. (ISh.)

(Fr.) b3:  [And hence,] نَكَسَهُ, and نَكَسَهُ إِلَى مَرَضِهِ, (tropical:)  It made him to fall back into his disease.] (TA, in art. هيض.)

(Msb.) Yousay, أَكَلَ كَذَا فَنُكِسَ (tropical:)  [He ate such a thing, and relapsed into his disease]. (A, TA.) and تَعْسًا لَهُ وَنُكْسًا, and sometimes one says, نَكْسًا, (S, K,) in this case, (S,) for the sake of mutual resemblance, (S, K,) or because نَكْسًا is a dial form [of نُكْسًا], (S,) [meaning, (assumed tropical:)  May he fall upon his face, or the like, (see art. تعس,) and relapse into disease: or] may he fall upon his face, and not rise after his fall until he fall a second time: and in like manner you say, ↓ تَعَسَ وَانْتَكَسَ. (Msb, art. تعس.) [See also 8.] You say also, نُكِسَ الجُرْحُ (assumed tropical:)  [The wound broke open again; or became recrudescent].

(K.) This last signification [understood figuratively] it is said to have in the phrase تَعَسَ وَانْتَكَسَ, a form of imprecation, meaning, (assumed tropical:)  May he be disappointed, or fail, of attaining his desire: for he who is overthrown in his affair (مَن انْتَكَسَ فِىأَمْرِهِ) is disappointed of attaining his desire, and suffers loss. (TA.) [See also 1, where this form of imprecation is differently explained.] b2: Also, i. q. نَكَّسَ رَأَسَهُ. (TA.)

ElFarezdak says, وَإِذَا الرِّجَالُ رَأَوْا يَزِيدَ رَأَيْتَهُم خُضُعَ الرِّقَابِ نَوَاكِسَ الأَبْصَارِ [And when the men see Yezeed, thou seest them depressed in the necks, lowering the eyes]: (S:) thus the verse is related by Fr and Ks: Akh  says, that it is allowable to say نَوَاكِسِ الأَبْصَارِ, after the manner of the phrase حُجْرُ ضَبٍّ خَرِبٍ; [see art. خرب;] and Ahmad Ibn-Yahyà adds ى in relating it; saying نَوَاكِسِى الأَبْصَارِ. (TA.)
