Consequences for one who does not adhere to Islam
Islam is the religion of Allaah, and it is the true religion. It is the religion which was brought by all the Prophets and Messengers. Allaah has prepared a great reward in this world and in the hereafter for those who believe in it, and He has prepared a severe punishment for those who disbelieve in it.
Allaah is the Creator and Sovereign, the One Who is in control of this universe, and you, O man, are part of His creation; He has subjugated to you all that is in the universe, and has prescribed His laws for you, which He has commanded you to follow. If you believe and obey what He has commanded you and keep away from what He has prohibited to you, then you will attain that eternal bliss which He has promised you in the Hereafter, and you will be happy in this world because of the different kinds of blessings which He will bestow upon you, and you will be akin to the most wise of creation and the purest in heart, namely the Prophets, Messengers, righteous and angels who are close to Allaah. But if you disbelieve and disobey your Lord, you will lose in this world and in the Hereafter. You will be exposed to His wrath and punishment in this world and in the Hereafter. You will be akin to the most evil and foolish of creation, and worse than the devils, wrongdoers, evildoers and false gods. This is in general terms.
I will explain to you something about the consequences of kufr, the details of which are as follows:
1 – Fear and lack of security
Allaah has promised those who believe in Him and follow His Messengers complete security in this world and in the Hereafter.
He says (interpretation of the meaning):
“It is those who believe (in the Oneness of Allaah and worship none but Him Alone) and confuse not their Belief with Zulm (wrong, i.e. by worshipping others besides Allaah), for them (only) there is security and they are the guided”
[al-An’aam 6:82]
Allaah is al-Mu’min (the Giver of security) and al-Muhaymin (the Watcher over His creatures); He is the Sovereign of all that exists in the universe. If Allaah loves a person for his faith then He will grant him security, tranquility and contentment. If a man disbelieves in Him He will take away his tranquility and security, so you will only see him either fearful about his destiny in the Hereafter, or fearing sickness for himself, or fearing for his future in this world. This is why the insurance business was established, to insure people’s lives and property, because of the lack of security and the lack of trust in Allaah.
2 – A life of hardship
Allaah has created man and has subjugated to him all that is in the universe. He has decreed for every creature its share of provision and its life span. So you see the bird going out from its nest in the morning to seek its provision, which it picks up, flying from branch to branch and singing the most beautiful songs. Man is one of these creatures whose provision and lifespan is already allocated. If he believes in his Lord and adheres to His laws, He will bless him with happiness and stability, and make things easy for him, even if he is only given the bare necessities of life.
But if he disbelieves in Him, and arrogantly refuses to worship him, He will make his life hard and fill him with worries and distress, even if he possesses all kinds of comforts and luxuries. Do you not see how many suicides in the world are committed by people who have all kinds of luxuries? Do you not see the extravagant spending on furniture and travel aimed at enjoying life? What makes people spend extravagantly is the fact that their hearts are devoid of faith, and their feeling that life is difficult and hard; it is an attempt to rid themselves of these feelings by ever-changing means.
Allaah indeed spoke the truth when He said:
“But whosoever turns away from My Reminder (i.e. neither believes in this Qur’aan nor acts on its teachings) verily, for him is a life of hardship, and We shall raise him up blind on the Day of Resurrection”
[Ta-Ha 20:124]
3 – He will live in conflict with himself and with the universe around him
That is because his own soul was created to believe in and worship Allaah alone (i.e., Tawheed).
Allaah says:
“Allaah’s Fitrah (i.e. Allaah’s Islamic Monotheism) with which He has created mankind”
[al-Room 30:30]
His body submits to its Creator, and acts in accordance with His system, but the kaafir insists on going against his own innate nature and lives in such a way that in matters where he is given a choice, he always chooses to follow the way which goes against the command of his Lord, so even if his body is surrendering to the laws of Allaah, in matters of choice he chooses to oppose the laws of Allaah.
He is in a state of conflict with the universe around him, because this entire universe, from the hugest galaxies to the tiniest insect is operating in accordance with the laws that Allaah has decreed for it.
Allaah says (interpretation of the meaning):
“Then He rose over (Istawa) towards the heaven when it was smoke, and said to it and to the earth: ‘Come both of you willingly or unwillingly.’ They both said: ‘We come willingly’”
[Fussilat 41:11]
Indeed, this universe loves the one who also submits to Allaah, and it hates the one who goes against that. The kaafir is the rebellious one in this universe, where he sets himself up in opposition to his Lord, rallying others to oppose Him too. Hence it comes as no surprise that the heavens and the earth and all creatures hate him and hate his kufr and heresy.
Allaah says (interpretation of the meaning):
“And they say: ‘The Most Gracious (Allaah) has begotten a son (or offspring or children) [as the Jews say: ‘Uzayr (Ezra) is the son of Allaah, and the Christians say that He has begotten a son [‘Eesa (Jesus)], and the pagan Arabs say that He has begotten daughters (angels and others)].’
Indeed you have brought forth (said) a terrible evil thing.
Whereby the heavens are almost torn, and the earth is split asunder, and the mountains fall in ruins,
That they ascribe a son (or offspring or children) to the Most Gracious (Allaah).
But it is not suitable for (the Majesty of) the Most Gracious (Allaah) that He should beget a son (or offspring or children).
There is none in the heavens and the earth but comes unto the Most Gracious (Allaah) as a slave”[Maryam 19:88-93]
And Allaah says of Pharaoh and his troops:
“And the heavens and the earth wept not for them, nor were they given a respite”
[al-Dukhaan 44:29]
4 – He will live in ignorance
For kufr is ignorance, indeed it is the greatest form of ignorance, because the kaafir is ignorant of his Lord and he sees this universe that He created in such an amazing way, and he sees how great is his own creation, then he ignores the One Who created this universe and Who created him. Is this not the greatest form of ignorance?
5 – He will wrong himself and wrong those around him
Because he is subjugating himself to something other than that for which he was created, and because he does not worship his Lord, rather he worships someone other than Him. Wrongdoing means putting something in the wrong place, and what wrongdoing is greater than directing worship to someone other than the One Who deserves it? Luqmaan the Wise said, explaining the abhorrent nature of shirk:
“O my son! Join not in worship others with Allaah. Verily, joining others in worship with Allaah is a great Zulm (wrong) indeed”
[Luqmaan 31:13 – interpretation of the meaning]
He also does wrong to others around him, humans and other creatures, because he does not recognize the rights of those who have rights. When the Day of Resurrection comes, everyone whom he wronged, whether human or animal, will stand before him and will ask his Lord to settle the score between them.
