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

Allaah (The Most High) said:

وَقَالَ الَّذِينَ كَفَرُوا لِلَّذِينَ آمَنُوا اتَّبِعُوا سَبِيلَنَا وَلْنَحْمِلْ خَطَايَاكُمْ وَمَا هُم بِحَامِلِينَ مِنْ خَطَايَاهُم مِّن شَيْءٍ ۖ إِنَّهُمْ لَكَاذِبُونَ

And those who disbelieve say to those who believe: “Follow our way and we will verily bear your sins,” never will they bear anything of their sins. Surely, they are liars. [Surah Al-Ankabut. Verse 12]

Imaam At-Tabari [may Allaah have mercy upon him] said: They (i.e. disbelievers of Quraish) said (to the believers), “Be upon the likes of what we are upon, such as our denial of the resurrection after death and that there will be no good recompense and punishment for the deeds of the people. If you follow our way in these affairs and are raised up after death (i.e. we doubt it), and you are recompensed for your deeds, we will indeed bear the burden of your sins”. [ Tafseer At-Tabari]

Imaam Ibnul Jawzi (may Allaah have mercy upon him] said that Mujaahid [may Allaah have mercy upon him] said, “This is the statement of the disbelievers of Quraish to those believers amongst the people of Makkah; they said to them, ‘Neither we nor you will be resurrected, so follow us. If anything is brought against you (i.e. we doubt it), the burden will be on us”. Allaah said that they (i.e. disbelievers of Quraish) are liars due to the claim that they will bear the sins of the (believers)’”. [Zaadul Maseer Fee Ilmit Tafseer By Imaam Ibnul Jawzi]

Imaam Ibn Katheer [may Allaah have mercy upon him] said: Allaah [The Most High] informed (us) about the disbelievers of Quraish that they said to those amongst them who believed (in the message of Muhammad) and followed the (right) guidance, “Abandon your religion, return to our religion and follow our way. We will verily bear your sins if you have any”, just as a person says, “Do this and your sin is upon my neck”. So Allaah declared their statement false, saying that never will they (i.e. the Quraish) bear anything of their (i.e. the believers) sins. Surely, they are liars. That is because no one will bear anything of the sins of others. [Tafseer Ibn Katheer]

Free mixing between men and women:

Imaam Ibnul Qayyim [may Allaah have mercy upon him] said, “There is no doubt that enabling women to free mix with men is the root of every calamity and evil. It is one of the major causes of sweeping divine punishment as well as one of the cause of corruption of the general and specific affairs. Free mixing between men and women is a cause of many immoralities and adultery, and it is one of the causes of widespread death and continuous plagues. When the prostitutes mixed with Musa’s [peace be upon him] army and immorality spread among them, Allaah sent a plague on them, and seventy thousand died in one day. The story is well-known in the books of Tafseer. One of the greatest causes of sweeping death is when adultery becomes rife, women are able to free mix with men and walk among them whilst dressed in an un-Islamic manner and beautified. If those in authority knew what is accompanied in this affair of corruption of this worldly affairs and the people – even before corruption in the religion, then indeed it would have been one the things they would more robustly seek to prevent”. [At-turuq Al-Hukmiyyah. page 281. slightly paraphrased]

Music:

 Allaah [The Exlated] said:

وَمِنَ ٱلنَّاسِ مَن يَشۡتَرِى لَهۡوَ ٱلۡحَدِيثِ لِيُضِلَّ عَن سَبِيلِ ٱللَّهِ بِغَيۡرِ عِلۡمٍ۬ وَيَتَّخِذَهَا هُزُوًا‌ۚ أُوْلَـٰٓٮِٕكَ لَهُمۡ عَذَابٌ۬ مُّهِينٌ۬
وَإِذَا تُتۡلَىٰ عَلَيۡهِ ءَايَـٰتُنَا وَلَّىٰ مُسۡتَڪۡبِرً۬ا كَأَن لَّمۡ يَسۡمَعۡهَا كَأَنَّ فِىٓ أُذُنَيۡهِ وَقۡرً۬ا‌ۖ فَبَشِّرۡهُ بِعَذَابٍ أَلِيمٍ

And of mankind is he who purchases idle speech to mislead (men) from the Path of Allah without knowledge, and takes it (the Path of Allah, the Verses of the Qur’an) by way of mockery. For such there will be a humiliating torment (in the Hell-fire). And when Our Verses (of the Qur’an) are recited to such a one, he turns away in pride, as if he heard them not, as if there were deafness in his ear. So announce to him a painful torment. [Surah Luqman Verses 6-7]

Imaam Abdul Azeez bin Baaz [may Allaah have mercy upon him] stated: The majority of the scholars say that the intent behind [لَهۡوَ ٱلۡحَدِيثِ – idle speech (in this verse)] refers to music. Some of them stated in addition that thsi also refers to the sounds of the flutes and (forbidden) instruments of amusement. This is the idle speech intended in this verse and it is one of the causes of misguidance from the path of Allaah and being misguided. Indeed, when the hearts are satiated with music, they become sick and hardened (i.e. corrupted); deviated and thus fall into misguidance. Listening to the Qur’an becomes difficult and they haughtly turn away from listening to it. It leads – those preoccupied with it – to corruption and deviation of the hearts- becomes hard for them to listen to the Qur’an and make them heedless through music. Abdullah Bin Mas’ood [may Allaah be pleased with him] said, “Singing (or music) grows hypocrisy in the heart as water makes plants grow”. This shows us the danger and evil of music and musical instruments.

It been transmitted in the Prophetic reports whose meaning show that music is forbidden, and from this reports is that Imaam Al-Bukhaari [may Allaah have mercy upon him] reported that the Prophet [peace and blessings of Allaah be upon him] said, “There will be people among my Ummah who will make lawful illegal sexual intercourse, the wearing of silk (i.e. for men even though only women are allowed to wear it), the drinking of alcoholic drinks and the use of musical instruments”. [Saheeh Al-Bukhaari 5590]

So the Prophet [peace and blessings of Allaah be upon him] informed us that during the end of time a people will make it permissible- even though it is forbidden – because of their weak Eemaan. (1)

Shaikhul Islaam Ibn Taymiyyah [may Allaah have mercy upon him] stated regarding the effect of music upon the souls: “It is the intoxicant of the souls. When the souls are intoxicated with the sounds (from music and musical instruments), Shirk (gradually) comes to them, they incline towards lewd acts and oppression, and thus they begin to commit Shirk, murder and fornication. These three deeds are present – a lot – amongst the people who listen to music”. (2)

Imaam Ibnul Qayyim [may Allaah have mercy upon him] said: That which we and others have witnessed and acquainted with based on experience, is that indeed musical instruments and instruments used for forbidden amusement do not appear amongst a people, spread amongst them and they busy themselves with it, except that Allaah (allows) their enemy to overcome them, and they are afflicted with famine, drought and evil rulers. (see footnote a) Therefore, the sensible person reflects on the state of affairs of the world and examines. And Allaah’s Aid is sought! (3)

Consequences of Persisting Upon Evil, Whilst Receiving More Provision

Allaah [The Exalted] said:

وَٱلَّذِينَ كَذَّبُواْ بِـَٔايَـٰتِنَا سَنَسۡتَدۡرِجُهُم مِّنۡ حَيۡثُ لَا يَعۡلَمُونَ
وَأُمۡلِى لَهُمۡ‌ۚ إِنَّ كَيۡدِى مَتِينٌ

Those who reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not. And I respite them; certainly My Plan is strong. [Surah Al-7:182-183]

“We shall gradually seize them with punishment” – Meaning, by granting them plentiful provision and respite until they think that they will neither be taken to task for their disobedience nor punished, so they increase in disbelief and transgression, and evil upon evil. And through this their punishment is increased and multiplied, so they harm themselves in ways they perceive not. (4) Imaam Sufyaan Ath-Thawree [may Allaah have mercy upon him] said, “Whenever they commit (major) sins, Allaah bestows a blessing on them and make them forgetful of seeking forgiveness. (5)
