On the Day of Judgement an angel will be in Jerusalem around Al-Aqsa. He will stand on a huge rock and he will cry calling, 'O you broken bones, O you crumbled bones, O you joined bones' and every single bone, crumbled, broken, joined, it will hear the call where ever it is and they will respond and come forward. The angel will cry out saying 'come forward for Allah's judgement.'
All the bones will come forward then Allah سبحانه وتعالى will say 'By my honor and my Majesty, every soul should go back to its body and come forward to Me.'
Allah will ask each soul to go back to the body for the Judgement to commence.
