In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Imam Ibn Al-Qayyim, may Allah have mercy upon him, said:

The basis of all sins – major and minor – are three: the heart’s attachment to other than Allah, going along with the intense strength of one’s anger and the intense urge of one’s desires. These three things constitute shirk, injustice and indecency (immorality). Shirk and invoking other than Allah is the heart’s attachment to other than Allah, murder is (related) to going along with one’s intense anger and fornication is going along with the intense urge of one’s desires. And because of this, Allah mentioned the three together in the verse:

وَٱلَّذِينَ لَا يَدۡعُونَ مَعَ ٱللَّهِ إِلَـٰهًا ءَاخَرَ وَلَا يَقۡتُلُونَ ٱلنَّفۡسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلۡحَقِّ وَلَا يَزۡنُونَ

And those who invoke not any other ilah (god) along with Allah, nor kill such life as Allah has forbidden, except for just cause, nor commit illegal sexual intercourse. [Al-Furqan. 68]

These three invite to one another – Shirk leads to injustice and indecency (immorality), just as Tawheed and Ikhlas turns a person away from them. Allah, The Most High, said:

ڪَذَٲلِكَ لِنَصۡرِفَ عَنۡهُ ٱلسُّوٓءَ وَٱلۡفَحۡشَآءَ‌ۚ إِنَّهُ ۥ مِنۡ عِبَادِنَا ٱلۡمُخۡلَصِينَ

Thus it was, that We might turn away from him (Yusuf) evil and indecency. Surely, he was one of Our chosen, guided slaves. [Yusuf. 24]

Meaning: turned him away from infatuation and illegal sexual intercourse.

Injustice leads to Shirk and indecency (immorality), because Shirk is the greatest injustice, just as Tawheed is the greatest justice. Justice is a companion of Tawheed and injustice is a companion of Shirk, and this is why Allah mentioned both together.

As for Tawheed and justice, Allah said:

شَهِدَ ٱللَّهُ أَنَّهُ ۥ لَآ إِلَـٰهَ إِلَّا هُوَ وَٱلۡمَلَـٰٓٮِٕكَةُ وَأُوْلُواْ ٱلۡعِلۡمِ قَآٮِٕمَۢا بِٱلۡقِسۡطِ

Allah bears witness that Laa ilaaha illaa Huwa (none has the right to be worshipped but He), and the angels, and those having knowledge (also give this witness); (He is always) maintaining His creation in Justice]. [Aal Imran. 18]

As for injustice and Shirk, Allah said:

إِنَّ ٱلشِّرۡكَ لَظُلۡمٌ عَظِيمٌ۬

Verily, Shirk is great injustice. [Luqmaan. 13]

Indecency (immorality) leads to shirk and injustice, especially when there is a strong desire that cannot be reached except through some type of injustice, such as seeking help through magic and shaytan. And indeed Allah mentioned both fornication and Shirk together in the verse:

ٱلزَّانِى لَا يَنكِحُ إِلَّا زَانِيَةً أَوۡ مُشۡرِكَةً۬ وَٱلزَّانِيَةُ لَا يَنكِحُهَآ إِلَّا زَانٍ أَوۡ مُشۡرِكٌ۬‌ۚ وَحُرِّمَ ذَٲلِكَ عَلَى ٱلۡمُؤۡمِنِينَ

The adulterer marries not but an adulteress, or a female polytheist and the adulteress none marries her except an adulterer or a male polytheist [and that means that the man who agrees to marry (have a sexual relation with) a female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer, or a polytheist)]. And the woman who agrees to marry (have a sexual relation with) a male polytheist or an adulterer, then she is either a prostitute or a female polytheist)]. Such a thing is forbidden to the believers [of Islamic Monotheism]. [An-Noor. 3]

These three [Shirk, indecency and injustice] can either be the cause of one another or lead to one another. And this is why whenever Tawheed in the heart is weaker and the Shirk in it is greater, it commits more indecency (immorality), becomes stronger in its attachment to images and infatuated with them. And what is similar to this is the statement of Allah:

فَمَآ أُوتِيتُم مِّن شَىۡءٍ۬ فَمَتَـٰعُ ٱلۡحَيَوٰةِ ٱلدُّنۡيَا‌ۖ وَمَا عِندَ ٱللَّهِ خَيۡرٌ۬ وَأَبۡقَىٰ لِلَّذِينَ ءَامَنُواْ وَعَلَىٰ رَبِّہِمۡ يَتَوَكَّلُونَ

وَٱلَّذِينَ يَجۡتَنِبُونَ كَبَـٰٓٮِٕرَ ٱلۡإِثۡمِ وَٱلۡفَوَٲحِشَ وَإِذَا مَا غَضِبُواْ هُمۡ يَغۡفِرُونَ

So whatever you have been given is but a passing enjoyment for this worldly life, but that which is with Allah (Paradise) is better and more lasting for those who believe (in the Oneness of Allah Islamic Monotheism) and put their trust in their Lord (concerning all of their affairs). And those who avoid the greater sins and indecency, and when they are angry, they forgive. [Ash-Shuraa. 36-37]

Allah informed us that what He has with Him is better for the one who believes in Him and relies upon him, and that is Tawheed. Then Allah said:

وَٱلَّذِينَ يَجۡتَنِبُونَ كَبَـٰٓٮِٕرَ ٱلۡإِثۡمِ وَٱلۡفَوَٲحِشَ

And those who avoid the greater sins and indecency.

Meaning, avoid the intense urge towards lowly desires. Then Allah said:

وَإِذَا مَا غَضِبُواْ هُمۡ يَغۡفِرُونَ

And when they are angry, they pardon.

This opposes the intense strength of anger.

Therefore, Allah mentioned Tawheed, pardon and justice together, and they are that which gathers every good. [1]

Whoever ponders upon the state of affairs of the world will find that every affair of rectification is due to Tawheed, singling out Allah in worship and obedience to His Messenger (Muhammad). And every evil in the world, trial, affliction, scarcity (in livelihood), being overpowered by an enemy and other than that is due to (our) opposition to the Messenger and the call to other than (the way of) Allah and His Messenger. Whoever truly ponders upon this and examines the state of affairs of the world- since its beginning and until the time Allah will take it away and those upon it- he will realise this regarding himself and others, in general and specific (circumstances). And there is no Might or Power except with Allah –The Most High, The Most Great. [2]

Every sin is a legacy inherited from a nation that was destroyed by Allah. Taking more than one is entitled to is a legacy from the people of Shu’ayb, peace be upon him. The corruption and arrogance displayed on earth are inherited from the people of Pharaoh, and the pride and tyranny are legacies from the people of Prophet Hud, peace be upon him. Thus, the sinner is adorned in the garments of these nations that are enemies of Allah. [3]

The pursuit of (vain) desires and prolonged (covetous) hope are the ingredients of every corruption, because the pursuit of (vain) desires blinds (one) from the truth in knowledge and intent, while prolonged (covetous) hope (makes one) forget the afterlife and hinders from making preparations for it. [4]

Everyone who possesses even a modicum of (sound) intellect is aware that the corruption of the world and its destruction are caused by placing human opinion ahead of divine revelation and desires ahead of sound reasoning. These two evil objectives cannot be deeply ingrained in a heart without causing its complete deterioration, nor exist in a nation without entirely corrupting its affairs. [5]

Allah, The Most High, said:

تِلْكَ الدَّارُ الْآخِرَةُ نَجْعَلُهَا لِلَّذِينَ لَا يُرِيدُونَ عُلُوًّا فِي الْأَرْضِ وَلَا فَسَادًا ۚ وَالْعَاقِبَةُ لِلْمُتَّقِينَ

That home of the Hereafter We assign to those who do not desire exaltedness in the earth or corruption. And the good end is for the pious ones. [28:83]

تِلْكَ الدَّارُ الْآخِرَةُ

“That home of the hereafter” – Meaning Paradise.

نَجْعَلُهَا لِلَّذِينَ لَا يُرِيدُونَ عُلُوًّا فِي الْأَرْضِ

“We shall assign to those who do not desire exaltedness upon the earth”.

Saeed Ibn Jubair said: “It is (those who do not desire) transgression”.

Ad-Dahhaak said: “It is (those who do not desire) oppression”.

Yahyah Ibn Sallam said: “It is (those who do not desire) shirk” and Muqatil said: “It is (those who do not desire to be) haughty by rejecting Iman”.

وَلَا فَسَادًا
“or corruption”.

Ikrimah said: “It is (those who do not desire) disobedience (to Allah and His Messenger)”.

Ibn Sa’ib said: “It is (those who do not) call to the worship of other than Allah”.

وَالْعَاقِبَةُ لِلْمُتَّقِين

“And the good end is for the pious ones”- Meaning, they will have a praiseworthy end. [6]
