When the soul is out of body then the angels get it to the first layer of the world of Nasoot wherefrom it has to begin its journey hereafter. If this soul is of a person who did not believe in hereafter or meeting Allah etc. or if he was a sinner and was away from straight path then this soul is imprisoned here or it wanders about in the first layer of Naasoot. Chapter An’am verse 31 says: “They are losers indeed who reject the meeting of Allah; until when the hour comes upon them all of sudden they shall say: “Alas, we neglected it.”
In the end of this verse and in the thirteenth verse Chapter Ankaboot sins have been described as loads by Allah. Therefore it will be very difficult for the soul which is a sinner to move and march forward. Among them there will be souls so heavy which will not be able to move at all. They will be lying at one place like a paralytic or sick person. However it will depend upon the quantity, number and nature of sins of each person. In the initial layer of Naasoot there is the torture of blazing fire and boiling water. Those souls who serve this punishment are carried there.

But those who are light and thin and strong because of their perfect faith, with belief and virtuous acts cross the Alam-i-Naasoot like lightening and reach their most exalted station in a very short period. The souls of pious and holy men, martyrs and saints are so light and thin and powerful that they reach their most exalted station in the twinkling of an eye and they do not even feel what time they have crossed the layers of hell. All the souls destined to heavens have their direction of journey towards Allah. For this reason it has been said: From Allah we come and to Him we return and it has also been said like this: All the souls are destined to die and then will return towards Me.

In this the word direction Allah has indicated the direction only. He has not said that it means to mingle and mix with Me as is said by some pious persons or common people. Allah has also said: “O man you have to strive and go on striving towards your Lord, then will you meet him” (84:6) He has also said: “ That you will climb from layer to layer” (84:19) Here layer to layer means the same and similar world of Alam-i-Misaal which have been already been described. It is apparent that layer is always one upon the other: Collateral parts are not called layers.

NOTE:
I want to tell here plainly that whatever have been described here and the language that has been used, for example, up and below, forward and backward, distant and near etc., all have been used just to explain the subject otherwise in the Alam-i-Misal and Alam-i-Amr there are not the similar measures of direction, time and distance as are in the material world.
