The Prophet ﷺ said regarding "the Day when mankind will stand before the Lord of the worlds" [Mutaffifin 83:6], "One of them will stand in his sweat up to the middle of his ears."
عن النبي ﷺ {يوم يقوم الناس لرب العالمين} [سورة المطففين: ٦] قال: يقوم أحدهم في رشحه إلى أنصاف أذنيه.
Bukhari related it in the Book of Raqaiq (6531), and Muslim in the Book of Paradise and the Description of Its Bliss and Its People (2862), both of them through the route of Isa bin Yunus, who said, Ibn Awn narrated to us, from Nafi, from Ibn Umar, and he mentioned it.
