If one truly believes in God, one understands that only God is permanent.
He was here before anything else, and He will be here after everything else is gone.
Everything else, and everyone else, is temporary.
So if one doesn’t believe in God, one’s existence doesn’t make any sense.
Life only makes sense if there is a God who can tell us why He created us and for what purpose.
Without God, we are nothing.
There are some attributes that man shares with God. After all, the purpose of man’s creation is to manifest in himself God’s attributes:
And when thy Lord said to the angels: ‘I am about to place a vicegerent in the earth.’ (2:31)
A vicegerent is a Prophet who manifests divine attributes and becomes an image of God.
As it says in the Bible, ‘So God created man in his own image.’ (Genesis 1:27)
The Holy Quran teaches that man has been created to serve as a manifestation of God’s attributes and to illustrate them in his life.
But man’s attributes are not the same as God’s attributes, just like an image is not the same as the real thing. Man is limited in his abilities to manifest God’s attributes, whereas God manifests these attributes fully.
For example man can create things out of other things, whereas God created the whole universe out of nothing.
Allah burdens not any soul beyond its capacity. (2:287)
The commandments of God are always given with due regard for human capacities and weaknesses.
All that man is expected to do is to sincerely strive after good, and avoid sin, to the best of his power, and the rest will be forgiven him by the Merciful God.
All that is on it will pass away. And there will remain only the Person of thy Lord, Master of Glory and Honor. (55:27-28)
The whole universe is subject to decay and death, and eventually is destined to perish. God alone will abide because He is Self-Subsisting, All-Sustaining, Independent and Besought of all.
And call not on any other God beside Allah. There is no God but He. Everything will perish but He. His is the judgment, and to Him will you all be brought back. (28:89)
Allah – there is no God but Him, the Living, the Self-Subsisting and All-Sustaining.
Slumber seizes Him not, nor sleep.
To Him belongs whatsoever is in the heavens and whatsoever is in the earth.
Who is he that will intercede with Him except by His permission?
He knows what is before them and what is behind them; and they encompass nothing of His knowledge except what He pleases.
His knowledge extends over the heavens and the earth; and the care of them burdens Him not; and He is the High, the Great. (2:256)
In the Holy Quran it says:
Those who look not for the meeting with Us and are content with the life of this world and feel at rest therewith, and those who are heedless of Our Signs – It is these whose abode is Fire, because of what they earned. (10:8,9)
As for those who do not believe in the Signs of Allah, surely Allah will not guide them, and they shall have a grievous punishment. (16:105)
As to those who believe not in the Hereafter, We have made their deeds appear beautiful to them, so they are wandering blindly. (27:5)
And whosoever will turn away from My remembrance, his will be a straitened life, and on the Day of Resurrection We shall raise him up blind. (20:125)
A person who consigns God to oblivion in this life, and leads a life which obstructs or impedes his spiritual development and growth, and thus deprives himself of heavenly light, will be born blind at the time of his second birth in the after life.
This will be because his soul in this life (which serves as a body for the much more spiritually developed soul in the next world) had become blind on account of his having led a sinful and depraved life in this world.
But whoso is blind in this world will be blind in the Hereafter, and even more astray from the way. (17:73)
