Shaikh Khaalid Adh-Dhufayree [may Allaah preserve him] stated:

بسم الله الرحمن الرحيم

All praise be to Allaah, and prayers and peace be upon Allaah’s Messenger, his family and companions, and those who follow his guidance. To proceed: These are some of the Aathaar As-Salafiyyah and Aqwaal Al-Athariyyah (1), which shows the obligation of hating and despising ahlul bidah (2) for the sake of Allaah, which I place in the hands of the seeker of truth and the one who follows the clear path to act upon them, and follows the path (or practice) of his Salaf. (3) These Aathaar make a people happy who follow the righteous predecessors, and anger others who hate the way of the path of the (pious) predecessors and accused them (i.e. the true followers of the pious predecessors) of khaarijiyyah. (4) We ask Allaah for wellbeing.

It is reported from Ibn Abbaas [may Allaah be pleased with him and his father] that he said, “There is not a people on earth who are more hated to me than the Qadariyyah (5) who come to me and dispute with me about Qadr, and that is only because they do not know Allaah’s Qadr, and that indeed Allaah [The All-Mighty and Majestic] cannot be questioned as to what He does, while they will be questioned”. [Reported by Al-Aajuree in Ash-Sharee’ah. page 213]

It is reported from Ibn Awn [may Allaah have mercy upon him] that he said, “There was no people more hateful to Muhammad – meaning Ibn Seereen [may Allaah have mercy upon him] – than people who newly invented that which they newly invented in this subject matter of Qadr”. [Reported by Al-Aajuree in Ash-Sharee’ah. page 219]

Shu’bah [may Allaah have mercy upon him] said, “Sufyaan Ath-Thawri [may Allaah have mercy upon him] used to hate ahlul ahwaa (6) and severely warned against sitting with them”. [Reported by Nasr Bin Ibraaheem Al-Maqdisee [may Allaah have mercy upon him] in Mukhtasar Al-Hujjah Alaa Taarik Al-Mahajjah. page 460]

Al-Qurtubi [may Allaah have mercy upon him] said, “Maalik (i.e. Imaam Maalik) used this Aayah as evidence for having enmity against the Qadariyyah and not to sit with them. Ash’hab [may Allaah have mercy upon him] reported from Maalik [may Allaah have mercy upon him] who said, ‘Do not sit with the Qadariyyah and I hate show them enmity for the Sake Allaah due to Allaah’s statement: [لا تجد قوماً يؤمنون بالله واليوم الآخر يوادون من حاد الله ورسوله – You will not find a people who believe in Allah and the Last Day having affection for those who oppose Allah and His Messenger]. [Tafseer Qurtubi 17/308] (7)

Al-Bayhaqi [may Allaah have mercy upon] him stated, whilst speaking about Ash-Shaafi’ee [may Allaah have mercy upon him], “Ash-Shaafi’ee dealt harshly against ahlul ilhaad (8) and ahlul bidah – openly declaring his hatred and boycotting them”. [Manaaqib Ash-Shaafi’ee. 1/469]

Ibnul Mubaarak [may Allaah have mercy upon him] said, “O Allaah! Do not allow one ascribed to religion [عندي يداً – i.e. find a way of influencing, associating with me etc] and thus my heart loves him”. [Reported by Al-Laalikaa’ee in Sharh Usool Ittiqaad Ahlia Sunnati Wal-Jamaa’ah 1/140]

One of the signs of the truth is having hatred for those who adheres to religion based on desires, and whoever loves the truth has to hate the ahlul ahwaa [people of desires] – meaning ahlul bidah”. [Seerah As-Saaliheen 3/1154 and Al-Hilyah 10/392 by Abu Nu’aym (may Allaah have mercy on both of them)]

Footnote 6: Who are Ahlul Ahwaa? [The People of Desires]: Shaikhul Islaam [may Allaah have mercy upon him] also said, “It is well known that the (act) of shunning by those who (express their) aversion or the love of those who are in agreement is neither an indication of the correctness nor corruption of a statement, except when it is based on guidance from Allaah; rather merely (utilising) a statement as proof (without guidance from Allaah) is tantamount to following desires. Allaah [The Most High] said: [ وَإِنَّ كَثِيرً۬ا لَّيُضِلُّونَ بِأَهۡوَآٮِٕهِم بِغَيۡرِ عِلۡمٍ‌ۗ – And surely many do lead (mankind) astray by their own desires through lack of knowledge]. [Surah Al-An’aam. Verse 119]

Allaah [The Most High] said: [ فَإِن لَّمۡ يَسۡتَجِيبُواْ لَكَ فَٱعۡلَمۡ أَنَّمَا يَتَّبِعُونَ أَهۡوَآءَهُمۡ‌ۚ وَمَنۡ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَٮٰهُ بِغَيۡرِ هُدً۬ى مِّنَ ٱللَّهِ‌ۚ – But if they answer you not (i.e. do not believe in your doctrine of Islamic Monotheism, nor follow you), then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah?] [Surah Al-Qasas. Verse 50]

And Allaah [The Most High] said to Dawud [peace be upon him]: [وَلَا تَتَّبِعِ ٱلۡهَوَىٰ فَيُضِلَّكَ عَن سَبِيلِ ٱللَّهِ‌ۚ – And follow not your desire for it will mislead you from the Path of Allah]. [Surah Saad. Verse 26]

Allaah [The Most High] said:

[ فَإِن شَهِدُواْ فَلاَ تَشْهَدْ مَعَهُمْ وَلاَ تَتَّبِعْ أَهْوَاء الَّذِينَ كَذَّبُواْ بِآيَاتِنَا وَالَّذِينَ لاَ يُؤْمِنُونَ بِالآخِرَةِ وَهُم بِرَبِّهِمْ يَعْدِلُونَ – Then if they testify, testify not you (O Muhammad) with them. And you should not follow the vain desires of such as treat Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) as falsehoods, and such as believe not in the Hereafter, and they hold others as equal (in worship) with their Lord]. [Surah Al-An’aam. Verse 150]

Allaah [The Most High] said:

قُلۡ يَـٰٓأَهۡلَ ٱلۡڪِتَـٰبِ لَا تَغۡلُواْ فِى دِينِڪُمۡ غَيۡرَ ٱلۡحَقِّ وَلَا تَتَّبِعُوٓاْ أَهۡوَآءَ قَوۡمٍ۬ قَدۡ ضَلُّواْ مِن قَبۡلُ وَأَضَلُّواْ ڪَثِيرً۬ا وَضَلُّواْ عَن سَوَآءِ ٱلسَّبِيلِ

Say (O Muhammad): “O people of the Scripture (Jews and Christians)! Exceed not the limits in your religion (by believing in something) other than the truth, and do not follow the vain desires of people who went astray in times gone by, and who misled many, and strayed (themselves) from the Right Path)”. [Surah Al-Maa’idah. Verse 77]

So whoever follows the desires of the people after (clarification of) the knowledge Allaah has revealed to His Messenger and the guidance He clarified for His slaves, then he (i.e. such a person) has a resemblance (to those regarded as followers of desires). And due to this, the proponents of religious innovations and factionalism – those who oppose the Qur’aan and authentic Prophetic path – were named Ahlul Ahwaa [the people of desires] by the pious predecessors, because of the fact that they accept what they love and reject what they hate based on their desires without guidance from Allaah. [Majmoo Al-Fataawaa 4/189-190]

Footnote 7: Listen here: Love & Hate for the Sake of Allaah by Abu Hakeem- By Shaikh Abu Hakeem: https://www.salafisounds.com/love-hate-for-the-sake-of-allaah-by-abu-hakeem/

Footnote 8: Ahlul ilhaad [Those guilty of ilhaad]. What is ilhaad? The word il’haad has a linguistic and customary meaning. Linguistically it means to turn away from obedience to Allaah, either by abandoning an obligation or committing something unlawful. Allaah said: [وَمَن يُرِدْ فِيهِ بِإِلْحَادٍ بِظُلْمٍ نُّذِقْهُ مِنْ عَذَابٍ أَلِيمٍ – And whoever inclines to evil actions therein or to do wrong (i.e. practice polytheism and leave Islamic Monotheism), him We shall cause to taste a painful torment]. [Surah Al-Hajj. Aayah 25]

So, based on this Aayah everyone who is disobedient to Allaah is a Mul’hid. However, il’haad is categorised into two types: a type that expels a person from Islam and it necessitates disbelief, and the type that does not expel a person from Islam and it necessitates sinfulness. As for the customary meaning, it is to reject the fact that Allaah alone has the right to be worshipped, rejecting Allaah’s existence, or a Muslim becoming an apostate.
