دَبُورٌ
1.
, used as a subst. and as an epithet, [of the feminine gender,] so that one says either رِيحُ الدَّبُورِ or رِيحٌ دَبُورٌ and simply دَبُورٌ, but more commonly used as an epithet, (M,) [The west wind: or a westerly wind: the west being regarded as the hinder quarter:] the wind that is opposite to that called
الصَّبَا (S, L, Msb, K) and
القَبُولُ, (L,) blowing from the direction of the place of sunset: (L, Msb:) or the wind that comes from [the direction of] the back, or hinder part, of the Kaabeh, going towards the place of sunrise: (M:) but IAth rejects this explanation: (TA:) or the wind that comes from the quarter behind a person when he is standing at the kibleh: [but this is a most strange explanation:] or, according to IAar, the wind that blows from the tract extending from the place where En-Nesr et-Táïr [or Aquila] sets [i. e. about W. 10° N. in Central Arabia] to the place where Suheyl [or Canopus] rises [about S. 29° E. in Central Arabia]: (M:) or that comes from the direction of the south (الجَنُوب), going towards the place of sunrise: (Msb:) it is the worst of winds: it is said that it does not fecundate trees, nor raise clouds: (Meyd, TA:) and in a tradition it is said that the tribe of 'Ád was destroyed by it: (T, TA:) it blows only in the hot season, and is very thirsty: (TA voce نَكْبَاءُ:) plural دُبُرٌ and دَبَايءِرُ. (M.) [Hence the saying,] عَصَفَتْ دَبُورُهُ وَسَقَطَتْ عَبُورُهُ [lit. His west wind, or westerly wind, blew violently, and his Sirius set: meaning (tropical:) his evil fortune prevailed, and his good fortune departed: for the دبور is the worst of winds, as observed above, and Sirius sets aurorally in the beginning of winter, when provisions become scarce].
