قُعَاصٌ

A certain disease which attacks sheep or goats, (S, A, K,) in consequence of which something flows from their noses, (TA,) killing them immediately, (S, A, K,) on the spot: (A:) and which kills men on the spot: (A:) and a certain disease in the breast, or chest, which is as though it broke the neck. (Lth, K.) It is said in a tradition, وَمُوتَانٌ يَكُونُ فِى النَّاسِ كَقُعَاصِ الغَنَمِ [And a mortality which shall be among men, like the قعاص of sheep or goats]. (S.)
