I think this is one of the most influential men in Islam today. His words in your links explain how antisemitism in Saudi Arabia and among Muslims is so virulent.
Here are a list of some of his other finding and rulings, according to Wikipedia.
Following the Pope Benedict XVI Islam controversy, he called the pope’s declaration “lies”, adding that they “show that reconciliation between religions is impossible”.
In 2007, he announced plans to demolish the Green Dome and flatten the tombs housed under it, including that of Muhammad.
In 15 March 2012, he declared that, “All churches in the Arabian Peninsula must be destroyed”. Abdulaziz bin Abdullah cited an Islamic hadith quoting the Prophet Mohammed on his deathbed. His declaration about the destruction of churches in the Arabian Peninsula led to negative comments. Roman Catholic bishops in Germany and Austria responded sharply to his fatwa, concerned about the human rights of non Muslims working in the Persian Gulf region. Russian Orthodox Archbishop Mark of Yegoryevsk said the ruling was “alarming”. Still, it seemed that most of the world overlooked the statement. Mehmet Görmez, the most senior imam in Turkey, another Muslim country, blasted the Saudi grand mufti’s call to “destroy all the churches” in the Persian Gulf region, saying that the announcement totally contradicted the peaceful teachings of the Muslim religion. Görmez, the president of Diyanet İşleri Başkanlığı (Presidency of Religious Affairs), said he could not accept the Islamic religious order—fatwa—issued by Grand Mufti Sheikh Abdulaziz Al ash-Sheikh, adding that the mufti’s declaration ran contrary to the centuries-old Islamic teachings of tolerance and the sanctity of institutions belonging to other religions.
In April 2012, he issued a fatwa allowing ten-year-old girls to marry insisting that girls are ready for marriage by age 10 or 12: “Our mothers and grandmothers got married when they were barely 12. Good upbringing makes a girl ready to perform all marital duties at that age.”
In June 2013, he issued a fatwa demanding the destruction of statues of horses placed in a roundabout in Jizan: “The sculptures [must] be removed because they are a great sin and are prohibited under Sharia (Islamic law)”.
The Grand Mufti issued a fatwa on September 12, 2013 that suicide bombings are “great crimes” and bombers are “criminals who rush themselves to hell by their actions”. Sheikh described suicide bombers as “robbed of their minds… who have been used (as tools) to destroy themselves and societies.”
On September 16, 2013 he condemned violence against non-Muslims living in Islamic countries or Muslims labeled as infidels. The Grand Mufti condemned acts that cause the “shedding of blood of Muslims and of those living in their counties in peace”. Abdul Aziz stated, “Given the dangerous developments in the Muslim world, I would like to warn against the danger of attacking Muslims and those (non-Muslims) under Muslim protection”.
“In view of the fast-moving dangerous developments in the Islamic world, it is very distressing to see the tendencies of permitting or underestimating the shedding of blood of Muslims and those under protection in their countries. The sectarian or ignorant utterances made by some of these people would benefit none other than the greedy, vindictive and envious people. Hence, we would like to draw attention to the seriousness of the attacks on Muslims or those who live under their protection or under a pact with them,” Sheikh Al-AsShaikh said, quoting a number of verses from the Qur’an and Hadith.
In late August 2014, he condemned the Islamic State of Iraq and the Levant and al-Qaeda saying, “Extremist and militant ideas and terrorism which spread decay on Earth, destroying human civilisation, are not in any way part of Islam, but are enemy number one of Islam, and Muslims are their first victims”.
On September 25, 2015, one day after the Mina crowd crush disaster which (according to the Associated Press) killed at least 1,399 foreign Muslims performing Hajj, Sheikh Abdul Aziz al-Sheikh publicly told Crown Prince Muhammad bin Nayef, who is also the country’s Minister of Interior and responsible for Mecca safety and security, that he was “not responsible for what happened”, and “as for the things that humans cannot control, you are not blamed for them. Fate and destiny are inevitable.” With his words, the Grand Mufti immunized Muhammad bin Nayef from possible public criticism within Saudi Arabia, which set the official death toll for the Mina tragedy at fewer than 800 deaths.
