Then God, the Oft-Forgiving, Most Merciful, The One Who sends Books and Messengers to mankind to lead them out of darkness and into light – will forgive all sins except one.
This is the greatest of all sins and the sin which all the prophets and messengers warned their people from first and foremost before all others.
Though God forgives the sins of the one who repents – if one arrives with this sin on the Day of Resurrection, God will not forgive it, meaning, that he will be subject to punishment some of which will never come to an end.
That sin, is polytheism.
The Call of The Messengers
God has said,
وَلَقَدْ بَعَثْنَا فِى كُلِّ أُمَّةٍ رَّسُولًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ وَٱجْتَنِبُوا۟ ٱلطَّٰغُوتَ فَمِنْهُم مَّنْ هَدَى ٱللَّهُ وَمِنْهُم مَّنْ حَقَّتْ عَلَيْهِ ٱلضَّلَٰلَةُ فَسِيرُوا۟ فِى ٱلْأَرْضِ فَٱنظُرُوا۟ كَيْفَ كَانَ عَٰقِبَةُ ٱلْمُكَذِّبِينَ
“And verily, We have sent among every nation a messenger (saying): “Worship God (alone), and avoid the false deities.” Then of them were some whom God guided and of them were some upon whom the straying was justified. So travel through the land and see what was the end of those who denied (the truth).”The Noble Qur’an 16:36
So despite the sins that were prevalent in the different times and places, the call of all the messengers, whether Noah, Abraham, Moses, Jesus or Muhammad, was to the worship of God, The One alone and to forsake the false deities.
This is the right of The Creator, The Owner, The Sustainer and it is the foundation of justice.
How can someone turn their worship to others besides or alongside God, when God owns them and whatever they worship?
How can someone worship something besides or alongside God, when God created them and the food they eat, sustains and protects them and nurtures them from being nothing worth mention to how they are now?
God has said,
لَقَدْ كَفَرَ ٱلَّذِينَ قَالُوٓا۟ إِنَّ ٱللَّهَ هُوَ ٱلْمَسِيحُ ٱبْنُ مَرْيَمَ وَقَالَ ٱلْمَسِيحُ يَٰبَنِىٓ إِسْرَٰٓءِيلَ ٱعْبُدُوا۟ ٱللَّهَ رَبِّى وَرَبَّكُمْ إِنَّهُۥ مَن يُشْرِكْ بِٱللَّهِ فَقَدْ حَرَّمَ ٱللَّهُ عَلَيْهِ ٱلْجَنَّةَ وَمَأْوَىٰهُ ٱلنَّارُ وَمَا لِلظَّٰلِمِينَ مِنْ أَنصَارٍ
They have certainly disbelieved who say, “God is the Messiah, the son of Mary.” But the Messiah said, “O Children of Israel, worship God, my Lord and your Lord.” Indeed, he who associates others with God – God has forbidden him Paradise, and his refuge is the Fire. And there are not for the wrongdoers any helpers.The Noble Qur’an 5:72
and He, The Most High, has said,
إِنَّ ٱللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِۦ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَآءُ وَمَن يُشْرِكْ بِٱللَّهِ فَقَدِ ٱفْتَرَىٰٓ إِثْمًا عَظِيمًا
“Indeed, God does not forgive that partners are set up for Him (and worshipped alongside Him) but He forgives whatever is less than that for whomever He wills”The Noble Qur’an 4:48
The Categories of Polytheism
Just as Monotheism is of Three Categories, so is polytheism of three categories.
No one can claim to be a monotheist, upon the religion of Abraham, Moses and Jesus, unless they purify themselves of all polytheism and become Monotheists as they were.
To do this they must complete the three categories of monotheism.
Monotheism of God’s Names and Atributes
This means to affirm for God everything which He affirmed for Himself, and negate from Him everything He negated for Himself, singling Him out in this.
God has revealed to us and preserved in His final and only preserved, unadulterated Revelation (The Qur’an and the way of His Messenger Muhammad) over 100 names, and from them are those which mean:
The Perfect Lord and Master Upon Whom all the creation depends, The All-Knowing, The All-Hearing, The All-Mighty, The All-Wise, The Creator, The Free of needs, The Originator, The Owner, The Lord and Nurturer, The Protector, The Bestower of Forms, The Great Provider, The Patron, The Helper The One Who Aids The Believers…
And from His Perfects Attributes are His Might, His Knowledge, His Wisdom, His Hearing, His Seeing, His Dominion, His Mercy, His Highness…
So whoever affirms for other than God any of these Names or Attributes, then He has committed polytheism and unbelief.
So whoever says that God has a single need, such as those who may say that He needs a blood sacrifice to forgive someone or that He needs a human intermediary to answer prayers, they have committed polytheism.
Likewise anyone who says that anyone that there is a Lord along with God, whether he is a prophet or otherwise.
Or that anyone ascribes God’s Knowledge, Will, Perfect Ability and Wisdom to atoms and molecules or nothingness like the atheists.
All of this is polytheism and God will not forgive the one who brings it on the Day of Judgment.
Monotheism of God’s Lordship
This category of monotheism is regarding God’s Perfect Actions.
His Lordship and Nurturing of all that exists.
For God is the only one who performs His Perfect Actions and from them are,
Creating, Providing Sustenance, Guiding, Misguiding (those deserving of it), Raising, Lowering, Owning, Granting Life and Granting Death, Decreeing, Commanding, Sending Revelation…
So like the above, if anyone attributes any of God’s Actions to other than Him, then he has committed polytheism and unbelief.
Whether it be that someone claims that there is something that exits out of His Decree for even a moment, like those who believe in the entity of luck or chance,
Or that someone believes that there is a thing called evolution that has the powers of creation,
Or that someone believes that a person provides sustenance independent from The Creator and Originator or that someone has attained wealth by their knowledge of the creation alone, and not that the knowledge they have been given is just one of the created ways and means God has used to provide them with sustenance.
All of this is polytheism which God will not forgive.
Monotheism of God’s Right to Worship
This is the monothesim that all the prophets and messengers were sent to call their people to.
It is the purpose for which God created mankind and it is the key to Paradise.
It is that you single out God in all worship, The only One deserving of it.
So if anyone directs worship to over than God, The All-Hearer, The All-Knower, then they have committed polytheism.
Whether that is supplication, praying, slaughtering, seeking aid, seeking forgiveness, seeking rescue, fearing, loving, seeking blessings, taking something as permissible or impermissible, or anything else from the acts of worship –
Then he has committed polytheism which God will not forgive.
If their life finished without seeking forgiveness and repenting they will be sunject to punishment.
How to Avoid Polytheism?
God has not left us without guidance.
He has preserved His Revelation until this time of ours – so those who wish to take a way to their Lord take it.
God has granted you your will and ability to choose between guidance and misguidance, so what will you choose?
You should know, that there will always be a group of God’s servants manifestly upon the truth, all the way up until God’s command comes.
Do not be dissuaded by the spread of misguidance around you, there was a time when Abraham was the only believer on the Earth, and none believed the prophets and messengers except a few.
The believer, the one who has submitted to God alone upon monotheism, turning away from polytheism and its people, need only call upon his Lord and He will answer him.
The name for this person in Arabic is a “Muslim” and this religion is “Islam”.
There are Muslims from every type of culture and walk of life, Black, White, Asian, Arabian, African and more besides.
How to Become a Monotheist
To become a monotheist upon the religion of Abraham (Islam), he must bear witness (with the tongue and the heart) that none has the right to be worshipped except God (The God of Jesus, Moses and Abraham, Who has no son or partner) alone and that Muhammad is His slave and messenger.
Whoever does this, rejecting everythign worshipped besides God alone, turning away from all invented religions and polytheism is a Muslim and has submitted in monotheism to God, The Most High.
This person is upon the straight path leading to God, the path of the prophets, steadfast affirmers of truth, the martyrs, and the righteous.
I ask God, The Perfect and Most High, to grant you refuge from harmful desires and doubts, to make you of those who grab ahold of and cling firmly to the truth and make you from among the righteous.
May He extol His messenger in the highest company of the Angels and grant him peace, his family and companions altogether.
