A’isha Radi allaho anha reported that she heard Allah’s Messenger Sallallaho Alaihey wasallam as saying: The people would be assembled on the Day of Resurrection barefooted, naked and uncircumcised. I said: Allah’s Messenger Sallallaho Alaihey wasallam , will the male and the female be together on the Day and would they be looking at one another? Upon this Allah’s Messenger (may peace be upon him) said: ‘A’isha, the matter would be too serious for them to look to one another
