حُسُومٌ
1.
Unluckiness, or inauspiciousness. (S, * K, * TA.) Some explain it thus in the passage here following. (S, * TA.)
2.
سَخَّرَهَا عَلَيْهِمْ سَبْعَ
لَيَالِ وَ ثَمَانِيَةَ أَيَّامٍ حُسُومًا, in the Qur'an, 69:7, means He sent it (the wind) upon them by force, (Jel,) or made it to prevail against them by his power, (Bd,) [seven nights and eight days] consecutively; (T, S, Bd, K, Jel;) an expression taken from the repetition of the act of cauterization, (T, Bd, Jel.) i. e. the act of the
حَاسِم; (Jel;) whence this word (حاسم) is applied to anything made consecutive; (T, TA;) and حُسُومٌ is its plural: (T, Bd, TA:) or حُسُومٌ signifies the making consecutive. and, as an epithet, consecutive, and continuous from first to last: (Fr, TA:) or, according to some, الأَيَّامُ الحُسُومٌ means the days that are consecutive with evil especially; and such ISd thinks to be the meaning: (TA:) or اللَّيَالِى الحُسُومُ means the nights that cut off good, or prosperity, (
تَحّسِمُ
الخَيْرَ,) from their people: (S, * K: [and the like is said by Bd in lxix. 7:]) or حُسُومًا in the Qur'an means causing them to pass away, come to an
end, cease, perish, or come to nought: (Zj, T:) or it may be a verbal noun, meaning for the purpose of cutting off: or a verbal noun of a verb meant to be understood, as a denotative of state; i. e.
تَحْسِمُهُمْ
حُسُومًا [agreeably with the explanation of Zj]; and this is confirmed by the reading with fet-h [i. e. حَسُومًا, though this is a very rare form of verbal noun]: (Bd:) you say أَيَّامٌ حُسُومٌ, (K,) in which case the latter word is a verbal noun used as an epithet, meaning cutting off, or preventing, good, or prosperity; (TA;) and أَيَّامُ حُسُومٍ, which has a similar meaning. (K, TA.)
