As Allah describes in the Qur'an...

As Allah describes in the Qur'an, He makes His good servants live a happy life, strengthens them with the spirit of faith, bring them out of the darkness into the light, and gives them a light by which they walk among the people; He has taken them under His protection and guardianship, and there is no fear for them, nor shall they grieve; He is with them, answers them when they call on Him, and remembers them when they remember Him; and the angels come down to them with good news of eternal peace.

Diametrically opposed to it is the condition of evil-doers. Allah causes them to err, takes them out of the light into the darkness, sets a seal upon their hearts and hearings, and a cover­ing over their eyes; He alters their faces turning them on their backs; places chains on their necks and these reach up to their chins, so they have their heads raised aloft, and makes a barrier before them and a barrier behind them, then He covers them over so that they cannot see.

He appoints for them the Satans to become their associates, and they turn them away from the right path while they think that they are guided aright; those Satans make their misdeeds to seem good to them and they are their guardians; Allah leads them on by steps from whence they perceive not; and yet He respites them, but His plan is firm; He makes a plan for them and leaves them alone in their rebellion, blindly wandering on. These are some examples of the conditions of the two groups.

On deeper consideration, it appears that man, in this world, lives two lives: there is this life which may be seen and perceived by all, and there is another life hidden behind this one; that hidden life is either good or bad - depending on his faith and deeds. Man will become aware of that hidden life when the veil of secrecy will be removed after death. Then he will see himself in his true form.

Further, it appears from the Qur'anic verses that man has had a spiritual life before the life of this world; and he shall have another life after this one. In other words, man has been given three lives - this life in this world is the second one, there was one preceding it and there will be another following. The con­dition of the third life shall be determined by that of this second life - which, in its turn, is governed by the first one.

Many exegetes have explained away the verses about the first life; they say that it is only a literary style, which presents imaginary pictures as real facts.
