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

Shaikhul Islaam Ibn Taymiyyah may Allaah [may Allaah have mercy upon him] said, “And when it is case that the true followers of the Prophets [peace and blessings of Allaah be upon him] are people of knowledge and justice, therefore the speech of the people of Islaam and the true adherents to the Prophetic Sunnah regarding the unbelievers and the proponents of religious innovations has to be based on knowledge and justice, and not conjecture and what the soul desires. And due to this the Prophet [peace and blessings of Allaah be upon him] said, ‘The judges are three- one will go to Paradise and two to Hell. A man who knows the truth and judges with it will enter paradise, a man who knows the truth but judges with the opposite of it will enter the fire, and a man who judges for the people based on ignorance will enter the fire’. [Reported by Imaam Abu Dawud 3573]

And when it is the case that the one who judges between the people in (affairs) of wealth, blood [i.e. murder cases, physical violence etc] and honour will enter the hell fire if he is not a just scholar, then how about the one who passes judgements – without knowledge and justice – on creeds, religions, the fundamentals of belief, divine knowledge and the general fundamental principles related to different subject matters, as is the case with ahlul bidah wal ahwaa [the proponents of religious innovations and desires]”. (1)

Al-Allaamah Abdur Rahmaan Bin Yahyah Al-Mu’allimee [may Allaah have mercy upon him] said, “The Imaams of Hadeeth are knowlegeable, well versed (in their field) and alert, and they guard against error their best, but they are of different levels in that”. (2)

Ibraaheem Ar-Ruhayli and His Tamyee (a)

Ibraaheem Ar-Ruhayli [may Allaah rectify his affair] stated, “It is obligatory to preserve the status and acknowledge the position of those scholars of Ahlus Sunnah who are known for their sound creed and Ijtihaad in aiding the Sunnah. It is not permissible to diminish their worth; declaring them innovators; accusing them of (following) desires or bigoted partisanship merely due to their mistakes in Ijtihaad”.

Response: Al-Allaamah Rabee Bin Haadi [may Allaah preserve him] responded to this statement of Dr Ruhayli and unveiled once again the reality behind this affair. He pointed out to Ar-Ruhayli that this statement of his is an indisputable affair (in the view) of Ahlus Sunnah regarding those who are known for their sound creed and ijtihaad in aiding the Sunnah- even though errors may occur from them in the intricate affairs of the religion and those affairs whose reality or evidence is not apparent to some people, however their status is preserved and their positions acknowledged. No one speaks ill of them except a person of desires just as is the case with the people of desires.
However, if the deviation is related to the manifestly clear affairs, such as when this claimant to the Sunnah defends the people of bidah and misguidance-those who propagate the falsehood of Wahdatul Wujood, negation of Allaah’s Attributes, revilement of the companions of the Messenger, the eternity of the souls and other than these clear affairs of misguidance; or he defends-by way of lies and treachery-those who hold the view regarding Wahdatul Adyaan, and other manifest affairs of misguidance, which are even rejected by (other) people of bidah and misguidance; and in addition to this he wages war against Ahlus Sunnah-seeking to devalue their scholars, considers them to be extremists and that they are from those who utilise odd speech when confronting the people of misguidance and when refuting their innovations; and in addition to this, he innovates false principles in order to contradict the fundamental principles of Ahlus Sunnah- [such as the false principle] “We rectify mistakes but we do not refute”, and some of them say, “We rectify mistakes but we do not destroy”, and the false principle, “I am not obliged” by way of which they seek to reject truth that is clear as the sun; and he also applies the term “Ahlus Sunnah Wal -Ittibaa” – to the people of bidah and the misguided paths that include affairs of Shirk, Bidah and Wahdatul Wujood; and he describes Ahlus Sunnah with the words scum, vile, extremists, blind followers, bigots and other wicked speech against Ahlus Sunnah; and in addition, he describes the Sahaabah with the word ‘Ghuthaa-scum’ and does not consider this description to be revilement if it is uttered by the likes of himself; (then) indeed with regards to this category of people whose state of affairs is as such, it is not permissible for a sane person- who is acquainted with the Sunnah and honours the Sunnah- that he considers such people to be from Ahlus Sunnah, or asking the people to preserve their status and acknowledge their ranks, or forbids the people from declaring them innovators, or forbids the people from accusing them of following desires and bigotry, despite the fact that their evil desires, affairs of misguidance, trials and illegal partisanship to the major people of misguidance are all manifest, whilst on the other hand their war against Ahlus Sunnah is clear and manifest, because indeed Ahlus Sunnah and their Imaams declare (a person) an innovator due to (affairs) that are far lesser than these calamities. And we find Imaam Ahmad [may Allaah have mercy upon him] saying about the one who reviles Ahlul Hadeeth: “Heretic”’ Ahlus Sunnah transmitted this ruling of Imaam Ahmad -and from them Shaikhul Islaam Ibn Taymiyyah [may Allaah have mercy upon him] who stated with emphasis, “That is because he (Ahmad) knew its significance”. Imaam Abu Zur’ah [may Allaah have mercy upon him] stated, “Whoever diminishes the worth of a single one amongst the companions of Muhammad, then he is a heretic”.’ Ahlus Sunnah transmitted this statement and no one opposed it. And here are the books of Aqeedah and the books of Jarh Wat-Tadeel in the presence of the people. Allaah (The Most High) stated:

يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَقُولُوا قَوْلًا سَدِيدًا
يُصْلِحْ لَكُمْ أَعْمَالَكُمْ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْ ۗ وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ فَقَدْ فَازَ فَوْزًا عَظِيمًا

O you who believe! Keep your duty to Allah and fear Him, and speak (always) the truth. He will direct you to do righteous good deeds and will forgive you your sins. And whosoever obeys Allah and His Messenger he has indeed achieved a great achievement (i.e. he will be saved from the Hell-fire and made to enter Paradise). [Soorah Al-Ahzaab. Ayah: 70-71] (3)

Muhammad Bin Haadi and His Ghuluww [Extremism]

As for Muhammad Bin Haadi, then must refer to the following link- Articles by Shaikh Abu Iyaad and Shaikh Abu Khadeejah regarding Al-Allaamah Rabee’s request for Muḥammad Bin Hādī to justify his tabdīʿ of Salafī students and shaykhs and to explicitly name the major scholars he accused of being “affected” and “destroyed” by the “Ṣaʿāfiqah” – one month, no answer.
