Salim bin Amir reported,

Miqdad bin Aswad said, "I heard the Messenger of Allah ﷺ say, 'On the Day of Resurrection, the sun will be brought near to creation until it is only a mile away from them.'"Salim bin Amir said, "By Allah, I do not know what he meant by 'mile.' Did he mean a measure of distance on the ground, or the kohl-stick used to apply kohl to the eye?"He continued, "People will be in sweat according to their deeds. Some will be in it up to their ankles, some up to their knees, some up to their waists, and some will be completely overwhelmed by sweat as if bridled by it."The narrator added that the Messenger of Allah ﷺ gestured with his hand toward his mouth.

Sahih

عن سليم بن عامر قال

حدثني المقداد بن الأسود قال: سمعت رسول الله ﷺ، يقول: تدنى الشمس يوم القيامة من الخلق، حتى تكون منهم كمقدار ميل. قال سليم بن عامر: فوالله ما أدري ما يعني بالميل؟ أمسافة الأرض، أم الميل الذي تكتحل به العين؟ قال: فيكون الناس على قدر أعمالهم في العرق، فمنهم من يكون إلى كعبيه، ومنهم من يكون إلى ركبتيه، ومنهم من يكون إلى حقويه، ومنهم من يلجمه العرق إلجاما قال: وأشار رسول الله ﷺ بيده إلى فيه.
