Whoever works righteousness, man or woman, and has Faith, verily, to him will We give a new Life, a life that is good and pure and We will bestow on such their reward according to the best of their actions. (Ch 16 V 97)
The human personality comprises of a physical and non-physical. The body represents the physical and the sprit represents the non-physical. Allah put both the physical and non-physical together for a particular reason. In order for us to understand we must remember two things, viz.
Allah says in Quran: “HE causes the night to go into the day and the day to go into the night”, meaning that the night and day are there for a specific period of time.
We must remember the incident of Hazrat Ibrahim (pbuh). Ibrahim (pbuh) was looking for God in material things, such as the moon and the stars. After some time he said “I won’t worship things that disappear”.
The point is that material things have a life span, e.g. the trees and flowers, and Allah testifies to this in the quran, “everything on the earth will go out of existence”. Allah mentions in Quran: “Whoever works righteousness, man or woman, and has Faith, verily, to him will We give a new Life, a life that is good and pure and We will bestow on such their reward according to the best of their actions” (ch 16 v 97). Therefore, our mission and purpose is to attain hayatan Tayyiba, a new life that is good and pure.
We should view all the trials and tribulations that befall us as a process that we must go through in order to prepare ourselves for hayatan Tayyiba.
Allah even gives us assurance at the time of death. HE mentions in quran “The true believers, at the time of death the angels will say to them do not worry, we are your walli, your closest companions at this time”.
