In Islam, Yawm al-Qiymah[ "the Day of Resurrection")is believed to be God's final assessment of humanity as it exists. The sequence of events (according to the most commonly held belief) is the annihilation of all creatures allowable, resurrection of the body, and the judgment of all sentient creatures/beings.
The exact time when these events are to occur is not specified; however, there are said to be major and minor signs which are to occur near the time of Qiyamah (end time). Many Qur'anic verses, especially the earlier ones, are dominated by the idea of the nearing of the day of resurrection

I think its actually a theory in Christianity to live back again after death which i am not sure if really happens . But again , this word has different meaning too ,where we can use this word for even getting a new life after a transformation in the person from bad to good...and so on..
