Assuming that your translation is accurate, it makes no sense.
Allama Zahid Al-Kauthari (RA) was a "Hanafi" and never claimed or gave a Fatwa/Answer is other Madhahib. Please ask Mufti Saheb (HA) to give example of where Allamah Saheb (RA) spoke of other Madhabs?
Allamah Saheb (RA) was a H-A-N-A-F-I as witnessed and written by Deobandi Ulama who met him in his lifetime.
Fact: Shaykhul-Islam was a political appointment by Islamic Governments, if a Mufti didn't back you he got sacked and became Shaytanul-Adham and thrown in prison. If a Shaytaan backed you he became Shaykhul-Islam
Today: Shaykhul-Islam is a title used by faboys and fangirls given out like candy and does not mean anything...
For disagreeing but...
Hazrat Mufti Zarwali Khan Saheb (HA) is making stuff up as there is no such thing as a definition of "Shaykhl-Islam"...His own words and application betray his own definition
This is another "strawberry Fatwa"
Allama Zahid Al-Kauthari (RA) neither claimed knowledge of all four (4) Madhabs, nor issued any such thing. In fact neither his supporters nor opposers ever claimed such a thing for him. No Deobandi such as Allamah Yusuf Binnori (RA) ever claimed such a definition. Hazrat Allama Zahid Al-Kauthari (RA) was called "Shaykhul-Islam" because he was the last Mufti of the Ottomans.
Instead of reading others, spend 30 seconds to read the first paragraph of Hazrat (RA)'s own Fatawa works:
Hazrat Allamah Anwar Shah Kashmiri (RA) and other Ulama called Hazrat Mufti Rasheed Ahmed Gangogi (RA) "Faqihun-Nafs" which is entirely different term.
Please feel free to check this post with a very Senior Alim as normal Ulama may or may not read or realize it, no disrespect intended
It is an obligation on a laymen to make Taqleed and it is an agreed upon opinion in Islam and there are no disputes. If you do not know then consult Ulama and leave the rest to Allah Ta'ala. It is not your business to know anything beyond that as a laymen.
You are required to SEEK an Alim with knowledge, Taqwa and the one who is trusted by other Uama and you are done.
You do not need to concern yourself with matters any further.
Where there is a legal dispute and Ulama disagree then the Qadha (judgement) of Qadhi lifts the disagreement. It is not because the Qadhi knows four Madhabs (yes he may be extremely knowledgeable) but it is his legal power which gives him the authority.
The obedience of Khaleefa (Caliph) is an obligation in Islam and the obedience of his (duly appointed representative) who in this case is the Qadhi.
Loading Qur'aan Verse
Imam Abu Yusuf (RA) the great student of Imam Abu Haneefa (RA) was a great Master of Hadeeth/Fiqh etc but he is knows as Qadhiul-Qudha (Chief Justice) not because of his knowledge (in which there is no doubt) but due to authority granted to him by Khaleefa Haroon Rasheed (RA).
Hazrat Muhammad Zahid al-Kawthari (RA):
He was a Master of knowledge and there is no doubt. But his authority was granted to him by the Ottoman Khaleefa. He had thousands of Ulama (and students) at his disposal whom he could consult on matters. He was the Chief Justice of the entire Ottoman Caliphate.
Like the Ottomans, during the Mughul Raj in India there were:
The entire (original) Dars-e-Nizami was designed to create these Qadhees so Muslims can get solutions to their problems according to Qur'aan and Sunnah and it did not teach all 4 Madhabs (it taught Hanafi Madhab because that was the need).
If you disagreed with their judgement you "may" get your head chopped off because you are openly in denial with the verse of Qur'aan.
A Qadhi does not need to know all 4 Madhabs, he has an entire staff under his authority who can do research and apprise of he situation. It is not his knowledge but his authority which matters.
A "Shaykhul-Islam" was a political title ordained by Khaleefa which granted the authority to:
This is how the system was supposed to work but unfortunately some of the pious lost their lives (or their positions) when they objected. Imam Al-Adham Abu Haneefa (RA) R-E-F-U-S-E-D to take the position was tortured and eventually gave his life but did not bow down to the Caliphate.
Imam Abu Yusuf (RA) his student saw the deteriorating circumstances and did the opposite Ijtehaad and felt that the Government of Khaleefa Haroon Rasheed (RA) needed direction of Ulama and accepted the job which his teacher had refused (previously).
The uniqueness of Hanafi Madhab:
Hanafi Madhab is extremely Khilafah (caliphate) heavy to the point where the establishment of Jumuah (Friday) Salah needs the ordainment of Khaleefa (Caliph) hence to this day (17NOV2019) many Hanafi Ulama pray Jumuah and then Pray Dhohar. The majority of Hanafi Ulama do not believe this to be necessary.
The collection and distribution of Zakat system (in the Hanafi system) is also very Khilafah (caliphate) heavy.
Modern example of Qadha:
We have no Khaleefa (caliph today) but certain issues still need to happen. The most common is for women to get their marriage annulled when there is a problem. This task used to be done by Qadhi but we longer have these so in our times it is "Shariah .council" which acts in this capacity.
Our biggest problem?
Our entire legal and judicial system is gone! Our poor can no longer get justice they keep going from court to court and whoever has most money can buy the most expensive attorney and make a mockery of justice. People are being oppressed, their rights are being trampled and nobody can do anything, its a joke.
Taliban system of Qadha:
A mother from Kandahar went to the Qadhi and complained to the Qadhi that her son is lazy and disrespectful. Qadhi sent a Toyota Hilux to the village to investigate with 2 Ulama. The 2 Ulama investigated in the morning and then after Dhohar the son was beaten in front of the Masjid and left only after he publicly apologized to his mother in front of the whole village.
He then promised in front of the whole village that he will get a job.
Do you think that Qadhi of Kandahar or the Ulama in Toyota Hilux knew 4 Madhabs? Let me change the question, do you think they needed to know 4 Madhabs? :P
No, its the authority which matters. When the British colonized India and Ottoman Caliphate was broken it is this authority of Ulama which has been taken away from Ulama. A "Fatwa" without authority is nothing and not enforceable and that is the problem with our people. People can speak non-sense against Qur'aan and Sunnah because there are no consequences.
Plenty in the past, right now in 2019 (UK)
As a policy, group only answers questions according to Hanafi Madhab but there are multiple Madhab Ulama in the Shura (group) and queries can be escalated to:
All 3 above have knowledge of all 4 Madhabs as I have witnessed for over 20 years, although they emphasise on Hanafi Madhab. I regularly ask them questions (in private) about other Madhabs for research etc
Maulana Yaqub Qasmi (HA) is a mountain of knowledge but sadly as you may be aware that Hazrat (HA) has memory issues now.
I am sure that there are many such Ulama in South Africa as well.
Qadhi Imran Falahi (HA) is one of the few qualified Qadhees in UK (there may be more) but I am not aware of them.
Jazakallahu Khayran for pointing out the deficiency in my post. I was commenting from a political point of view and Mufti Saheb has commented on the issue holistically.
This cannot be undone and I am sure it will be greatly appreciated.
