Narrated `Abdullah bin `Umar:
حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ ، حَدَّثَنَا مَعْنٌ ، قَالَ حَدَّثَنِي مَالِكٌ ، عَنْ نَافِعٍ ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " {يَوْمَ يَقُومُ النَّاسُ لِرَبِّ الْعَالَمِينَ} حَتَّى يَغِيبَ أَحَدُهُمْ فِي رَشْحِهِ إِلَى أَنْصَافِ أُذُنَيْهِ " .
The Prophet (ﷺ) said, "On the Day when all mankind will stand before the Lord of the Worlds, some of them will be enveloped in their sweat up to the middle of their ears."
