رَيْب

rayobN * is an inf. n. of 1, (T, M, Mgh, Msb, &c.,) as also ↓ riybapN , (M, K,) or the latter is a simple subst.: (S, Msb:) the primary signification of the latter [and of the former also when it is used as a simple subst.] is Disquiet, disturbance, or agitation, of mind: (Ksh and Bd in ii. 1:) [and hence] the former signifies doubt; (T, S, Msb;) as also ↓ the latter; (S, Mgh;) because doubt disquiets, or disturbs, the mind: (Ksh and Bd ubi suprà, and Mgh:) and opinion; syn. Zan~N : (Msb:) and ↓ the latter, (S, M, A, Mgh, K,) and the former also, (M, A, K,) doubt, or suspicion or evil opinion; syn. tuhamapN (S, M, A, Mgh, K) and Zin~apN : (M, A, K:) or the former, [and ↓ the latter also,] doubt combined with suspicion or evil opinion: (IAth, TA:) and a thing, or an event, or a case, that occasions one doubt, or suspicion or evil opinion, or doubt combined with suspicion or evil opinion; i. e. maA raAbaka mino A^amorK : (S, TA:) [in this last sense, the latter is the more common: hence,] lying is termed riybapN in a trad. cited above: see 1: (Mgh:) the ↓ pl. of the latter is riyabN . (Msb.) A man, and a thing or an event or a case, is said to be ↓ *uw riybapK [as meaning Having in him, or it, something occasioning doubt, or suspicion &c.]. (A.) [ laA rayoba often occurs as meaning There is no doubt; without doubt; undoubtedly. ] ― -b2- Hence, rayobu Alz~amaAni The accidents, or evil accidents, of time, (Ksh and Bd ubi suprà, [in Fleischer's ed. of the latter riyab AlzmAn , which is more agreeable with the explanation, but rayob AlzmAn is more usual,]) that disquiet, or disturb, the minds and hearts: (Ksh:) and rayobu Almanuwni (S, A) [which likewise signifies] the accidents, or evil accidents, of time: (S:) and rayobu Ald~ahori signifies the same; i. e. Sarofuhu , (M, K,) or Suruwfuhu , (T, Msb,) and HawaAdivuhu . (T. [This is said in the TA to be tropical; but I do not find it so characterized in the A.]) ― -b3- [Hence, likewise,] rayobN also signifies A want; a needful, or requisite, thing, affair, or business; syn. HaAjapN . (S, A, Msb, K.) A poet says, (S,) namely, Kaab Ibn-Málik El-Ansáree, (TA,) qaDayonaA mino tihaAmapa kul~a rayobK wa xayobara vum~a A^ajoyayonaA Als~uyuwfaA [ We accomplished, from Tihámeh, every want, and from Kheyber: then we gave rest to our swords ]. (S.) -A2- [ ryb mentioned by Freytag as applied in art. dls of the S to a certain plant, and written rayob in both of my copies of the S in that art., is a mistake for rabab , which is the reading in the TA, pl. of rib~apN .]
