"Then you will drink like the drinking of thirsty camels," meaning: the thirsty camels; according to the Tafsir of al-Kalbi.
Muhammad said: A camel is called "ahyam" (thirsty) and a female camel is called "hayma'."
﴿فشاربون شرب الهيم﴾ يَعْنِي: الْإِبِل العطاش؛ فِي تَفْسِير الْكَلْبِيّ.
قَالَ محمدٌ: بعيرٌ أهْيَمُ وناقة هيماء.
