This natural universe (dunya) is not eternal. It has started at a certain time and will reach to its end at a certain time. This earth, the sun, the moon and all stars and planets will be destroyed before the resurrection. This fact is expressed by many verses of the Glorious Qur’an such as the following:
“When the sun is covered, and when the stars darken, and when the mountains are made to pass away, and when the camels are left untended, and when the wild animals are made to go forth, and when the seas are set on fire, and when souls are united,” (81:1-7)
Therefore, everything in this universe has a certain end. Our bodies are mortal. Our physical lives, our powers, our youth, fame and beauty are mortal (perishable). Allah is eternal and the spiritual (abstract) universe is also endless. Our spirits belong to the spiritual universe and not to the corporeal universe.
“And they ask you about the spirit Say: The spirit is from the commands of my Lord, and you are not given ought of knowledge but a little.” (17:85)
And if we notice that our spirits make our personality and reality, we easily come to the conclusion that death is not our end. Death is like a gate to another universe. Not only our spirits but also our characters and acts will be preserved. (In the next chapter we will discuss the embodiment of our actions.)
Thus, we cannot obtain eternity and infinite life or endless pleasure in this world. if we want them, we should know they are due to the relationship with Allah. Because Allah is eternal, everything is related to Him (in a narrow sense), is of His signs, and shows Him and so, must be like Him.
“Everyone on it must pass away And there will endure for ever the face (wajh) of your Lord, the Lord Of glory and honour.” (55:26,27)
“And call not with Allah any other god; there is no god but He; every thing is perishable but His face (wajh); He is the judgement, and to Him you shall be brought back” (28:88)
In Arabic “wqjh” is that part of any thing through which you can confront that thing. For example if you confront the foot or hand of a person, you are not confronting and meeting him, but when you confront his face and have a kind of face to face sight, you confront and meet him. This is why in Arabic our face is called “wajh”. In the case of Allah, we know that He has no body, so it is not necessary to look in a special direction to meet Him. In the Glorious Qur’an this fact is expressed in the following verse:
“And for Allah is the East and the West, therefore, whither you turn, thither is Allah face Surely Allah is Ample-giving, Knowing.” (2-115)
As we can consider and use everything to know Him, to reach Him, so every thing can be called “wajh Allah”. Those things which are considered in this way will never be destroyed as we saw in the verses: (55:26,27) and (28:88). So every action or even intention which you have for His pleasure will be preserved. if you give some money to a poor person, this money will be destroyed but that aspect of this money or in other words that aspect of this action which is “wajh Allah” will be preserved forever.
