Qiyamat On Earth
Their bodies will be raised from Earth, just like their first bodies were given to them. The personality i.e. the nafs of a human being is a metaphysical concept which comes into existence as an amar of Allah ( through nafkh-e-ruh ) and lies in a place called Barzakh as per Quran after death of a human being, and we have not been given knowledge where that place exists. Therefore, no matter wherever a human being dies, their nafs (soul) would be preserved in Barzakh and will be returned to their new bodies given to them on the day of judgement. For concept of Barzakh , please see: Discussion 34711
