Soul is from the matters of the unseen and nothing can be said in its explanation without established proofs from the Book and the Sunnah. The knowledge required for our welfare in this world and the Hereafter has been conveyed to us by the Messenger of Allah (sallallahu alaihe wa-sallam), and there is no need to seek any goodness beyond that.
The Soul is a creation of Allah, whose function is to bring life to the human body. It remains with the human body throughout the life and departs at death. After which the souls are either held in Paradise or punishment. There is no returning back of the souls of the righteous people from Paradise, and no escaping of the souls of evildoers from the punishment of the grave. Therefore, pious or evil, the souls do not return to this world, neither to take revenge nor to assist the living. Neither is there any concept in Islam, which explains that justice is dependant upon the soul's coming back and setting things aright
