The Foundations And Concepts of Islam
But if you disbelieve, and disobey your Lord; you will lose your worldly life and your Hereafter and expose yourself to His wrath and punishment in this world and the Hereafter. You will then be like the most wicked of all creatures, the most defective in intelligence and the most debased in mind: the devils, corrupt people and false deities and transgressors, just to mention a few.
Let me now tell you something of the consequences of disbelief in detail:
1. Fear and lack of security: Allaah promises complete security in this world and the Hereafter for those who believe in Him and follow His Messengers. He says,
"Those who believe and confuse not their belief with wrong, for them there is security and they are the guided."
Allaah is the Giver of security, the Watcher over His creatures, the Possessor of all that is in the universe. If He loves a slave of His because of his belief, He gives him security, tranquillity and peace, but if a slave of His disbelieves in Him, He withdraws tranquillity and security from him and you will not see such a person but afraid of his fate in the Hereafter, afraid for his own self from calamities and diseases and afraid for his future in this world. That is why the insurance market insures lives and properties for lack of security and lack of having trust in Allaah.
2. Difficult life: Allaah created man, subjected to him all that is in the universe and portion out for every creature his share of sustenance and lifespan. Hence you see the bird going out of its nest to look for its provision and then picks it. It moves from a branch of the tree to another and sings in most melodious tone. Man is also one of these creatures for whom Allaah has portioned out his provision and lifespan. If he therefore believes in his Lord and stands firm on His Law, Allaah will give him happiness and stability and He will make his matters easy for him, even if he does not possess more than the least means of livelihood.
If he however disbelieves in his Lord and feels too big to worship Him, He will make his life straitened and make him suffer from sorrow and distress even if he has all means of comfort and enjoyment at his disposal. Don't you see the great numbers of suicide victims in countries in which all means of affluence are guaranteed for their citizens? Don’t you see all kinds of furniture and mats used for the enjoyment of this life? The cause of all this extravagance is the vacuity of the heart from faith, feeling of constraint and hardship and an attempt to dismiss all these worries with all different means. Allaah says the truth in His Word,
"But whoever turns away from My Reminder, verily, for him is a life of hardship and We shall raise him up blind on the Day of Resurrection."
3. He will live in continuous war with his own soul and with the world around him.
