Muqbil bin Hadi al-Wadi'i

Wadi'i was born sometime during the late 1920s and early 1930s near the city of Sa'adah in northern Yemen.

He was said to be from a Zaydi tribe, and he was initially a Zaydi Shia.

He left Yemen as a young man and travelled to Saudi Arabia to work and became acquainted with Sunni works of Islamic scholarship.

After finishing primary education in Yemen, Wadi'i spent roughly two decades studying Islam in Saudi Arabia.

In 1963 he began by studying at the Salafi teaching centre developed by Muhammad ibn al Uthaymeen in Najran before then being accepted to study at the Islamic University of Madinah where he attended Halaqas led by Hadith scholar Muhammad Nasiruddin Al-Albani and Abdul-Ghaffar Hasan Al-Hindi as well as former Grand Mufti Abd-al-Aziz ibn Abd-Allah ibn Baz while also studying under Muhammad al-Sumali.

Wadi'i is said to have graduated from the Islamic University of Madinah with a master's degree in the science of hadith.

In 1979, his stay in Saudi ended abruptly when he was indicted on suspected involvement in the Grand Mosque Seizure.

After spending a few months in prison, Grand Mufti ibn Baz negotiated his release, though Wadi'i was forced to return to his home country where he would eventually become known as the father of the modern Salafi movement within Yemen.

It was there that he began to spread the Salafi Da'wah in Yemen, with much initial opposition from the local Shafi`is, Ismailis and Zaidis.

Wadi'i went on, soon after his return to his native region, to found and establish an institute that he named Dar al-Hadith al-Khayriyya in Dammaj.

It would become one of the most important and influential educational institutions for Salafism in the world, teaching tens of thousands of students ranging from the Arab world to Africa to Southeast Asia and the Western world.

It was during this time that Wadi'i, along with Ja'far 'Umar Thalib, established close ties between Yemeni and Indonesian Salafis.

In the 1980s Wadi'i accepted grants from various sources such as Ibn Baz and the Saudi Government of 15,000 Saudi Riyals every two months.

However, his continued critique of the Saudi monarch, due to his believed wrongful imprisonment, led him to be more independent in the financing of the institute's operations.

He stated that managing the mosque and institute in Dammaj required little funding and was easily covered by local donations and zakat.

Wadi'i was opposed to the rapid expansion of the Muslim Brotherhood movement across Yemeni schools in the 1980s, and opened the Dar al-hadith religious institute in Dammaj in order to rebut Islamist movements.

His Dar ul-Hadith seminary and institute of Dammaj was known to oppose al-Qaeda and other radical extremist organisations, as Wadi'i himself stated in an interview with Hassan al-Zayidi of the Yemen Times in 2000.

In terms of Islamic jurisprudence, al-Wādi'i did not follow any established school of thought in Islam and opposed the practice of Taqlid, or subordination to higher legal authority.

His views on the principles of Islamic jurisprudence were almost identical with those of the Zahiri school; he rejected the usage of Qiyas, or analogical reasoning, in deriving rulings in Islamic jurisprudence entirely, recommending the books of Zahiri scholar Ibn Hazm in the principles of jurisprudence for details on the topic.

al-Wādi'i was fond of the works of Ibn Hazm, to the point that, when asked about Ibn Hazm's Zahirism, he advised every Muslim "to be a Zahiri."

Muqbil bin Hadi bin Muqbil bin Qa’idah al-Hamdani al-Wadi’i al-Khallali (1933 – 21 July 2001) (مقبل بن هادي الوادعي) was an Islamic scholar in Yemen.

He was the founder of a Madrasa in Dammaj which was known as a centre for Salafi ideology and its multi-national student population.

Muqbil was noted for his fierce criticisms of the Egyptian Islamist scholar Sayyid Qutb.

After a prolonged illness, and hospital treatment in Jeddah, Saudi Arabia, Cologne,Germany and Los Angeles, California, Wadi'i died on July 21, 2001, from either cirrhosis or liver cancer.

His funeral prayer was performed in the Masjid al-Haram in Makkah and he was laid to rest in the Al-'Adl cemetery close to the graves of Ibn Baz and Muhammad ibn al Uthaymeen.

After his death, reports continued to surface of changes in curriculum and power struggles at the Dar al-Hadith, although these rumours were dispelled a few years later by contemporary Muslim scholar Rabee al-Madkhali.

Joint Task Force Guantanamo counter-terrorism analysts prepared Summary of Evidence memos offering justifications for continuing to hold them in extrajudicial detention.

Several of the captives had their detention justified, in part, through their association with Al Wadi.

Wadi'i made a number of statements against terrorism and attempted to advise Osama bin Laden against it, whom he blames - along with older movements like the Muslim Brotherhood - for many of the problems Muslims face today; he further commented in an interview:

I did in fact send my advice and warning (to bin Laden) but only Allah knows if it actually arrived or not.

However, some of those people did come to us, offering their help and assistance in preaching and calling to Allah.

Afterwards, we found them sending money, requesting that we distribute it among the leaders of various tribes; they were trying to buy rocket-launchers and machine guns.

But I refused them and told them to never come to my house again.

I made it clear to them that what we do is preach only and we don’t allow our students to do anything but that.

Waadi'ee had earlier authored a book as well, referring to bin Laden as the head of all "sectarianism," "partisanship," "division," and "religious ignorance," and accusing him putting money into weapons while ignoring his religion.

Additionally he was a huge supporter of the controversial Saudi preacher Rabi'i ibn Hadi al-Madkhali.

Feircly critiquing the Muslim Brothers, Wadi'i states:"'They [the Muslim Brotherhood] are bankrupt as it relates to knowledge and bankrupt as it relates to Daʿwah... The founder of this group – which is Ḥasan al-Bannā – used to make Ṭawāf around the graves...They [the Muslim Brotherhood] are prepared to cooperate with the Devil against Ahl al-Sunnah.”"

Wadi'i was also a staunch critic of the scholar Muhammad ibn Salih al-Munajjid, said that he's a misguided "Sururi".

In 2014, Wadi'i's institute, Dar al-Hadeeth would be shut down after a long Siege of Dammaj by Houthi rebels.

The manager of the institute, Yahya al-Hajuri, as well as thousands of foreign students were forced to relocate to Al Hudaydah Governorate.
