Sahih Muslim Book 53, Hadith 66
By Allah, this world (is so insigni- ficant in comparison) to the Hereafter that if one of you should dip his finger- (and wnile saying this Yahyg pointed with his forefinger) -in the ocean and then he should see as to what has stuck to it. This hadith has been narrated through another chain of transmitters also but with a slight variation of wording.
If you live for a time, you would certainly see people get up (in the morning) in the wrath of Allah and getting into the evening under the curse of Allah, and there would be in their hands (whips) like the tail of an ox.
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 Allah's Messenger (ﷺ) said: 'A'isha, the matter would be too serious for them to look to one another.
