Uqba bin Amir reported,

I heard the Messenger of Allah ﷺ say, "The sun will draw near to the earth and people will sweat. Some will have sweat reaching their ankles, some up to the middle of their shins, some up to their knees, some up to their backsides, some up to their waists, some up to their shoulders, some up to their necks, and some up to the middle of their mouths." He gestured with his hand, placing it across his mouth like a bridle. I saw the Messenger of Allah ﷺ make this very gesture. "And some will be completely submerged by their sweat," and he struck with his hand to indicate this.

Ahmad 17439

سمعت رسول الله ﷺ يقول تدنو الشمس من الأرض فيعرق الناس فمن الناس من يبلغ عرقه عقبيه ومنهم من يبلغ إلى نصف الساق ومنهم من يبلغ إلى ركبتيه ومنهم من يبلغ العجز ومنهم من يبلغ الخاصرة ومنهم من يبلغ منكبيه ومنهم من يبلغ عنقه ومنهم من يبلغ وسط فيه وأشار بيده فألجمها فاه رأيت رسول الله ﷺ يشير هكذا ومنهم من يغطيه عرقه وضرب بيده إشارة
