Sahih Muslim 2859a
'A'isha reported that she beard Messenger of Allah ﷺ as saying: The people would be assembled on the Day of Resurrection barefooted, naked and uncircumcised. I said: Allah's Messenger, will the male and the female be together on the Day and would they be looking at one another? Upon this Messenger of Allah ﷺ said: 'A'isha, the matter would be too serious for them to look to one another.
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ حَاتِمِ بْنِ أَبِي صَغِيرَةَ، حَدَّثَنِي ابْنُ أَبِي مُلَيْكَةَ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ، قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " يُحْشَرُ النَّاسُ يَوْمَ الْقِيَامَةِ حُفَاةً عُرَاةً غُرْلاً " . قُلْتُ يَا رَسُولَ اللَّهِ النِّسَاءُ وَالرِّجَالُ جَمِيعًا يَنْظُرُ بَعْضُهُمْ إِلَى بَعْضٍ قَالَ ﷺ " يَا عَائِشَةُ الأَمْرُ أَشَدُّ مِنْ أَنْ يَنْظُرَ بَعْضُهُمْ إِلَى بَعْضٍ " .
