aselemu aleikum brother....
i wish any human being knew the answer to your question..but instead nobody knows except for ALLAH ta3ala.
all we know about yaum a deen (judgement day) is that there is no escaping it, every human being will experience this day...may ALLAH ta3ala have mercy upon us..
''a sa3a la rayba fieha''
there are good books though that have ''3alamat of yaum al qiyamah'' signs of this day being very close...i reccomend you to read such books..they are very very interesting brother
