Ali al-Sistani

Pope Francis and Grand Ayatollah Ali al-Sistani met on 6 March 2021 during Pope Francis's visit to Iraq. They met for about 40 minutes in the Shiite cleric's home in Najaf. The visit was prepared with great care to details, such as how many meters the Pope will walk to al-Sistanis home or on what seating arrangements the two will take a seat.

Sistani said the Iraqi government and police were liable for the killing of protestors during the 2019–2021 Iraqi protests. He requested that the government prosecute those who gave the command to shoot protesters. The ayatollah rarely voices his opinion on politics except in extreme unrest. The protests have been described as Iraq's worst violence since ISIL was militarily defeated in 2017. A month later in November 2019, in response to the death of three Iraqi protesters, Sistani said "No person or group, no side with a particular view, no regional or international actor may seize the will of the Iraqi people and impose its will on them."

On 13 June 2014 Sistani appealed that Iraqis should support the government against the Islamic State of Iraq and the Levant militant group which had taken over Mosul and Tikrit and was threatening Baghdad. Later in June 2014, Sistani revised his statement and issued a fatwa calling for "citizens to defend the country, its people, the honor of its citizens, and its sacred places," against the ISIL.

In January 2010, during a Jumu'ah khutba (Friday sermon), Saudi scholar Mohamad al-Arefe vehemently criticized al-Sistani by referring to him as an atheist and by describing his behavior as "debauched". The remarks prompted protest by his followers in Iraq, Qom and Lebanon. Iraqi Prime Minister Nouri al-Maliki rebuked the Saudi religious authorities. Lebanon-based Islamist militant organization Hezbollah also condemned the attack on al-Sistani, calling the speech "inauspicious," while praising al-Sistani as one of Shia Islam's "most prominent religious references."

On 18 September 2008, hackers attacked hundreds of Shia websites. The attacks were reportedly the work of a Muslim faction known as group-xp, based in the Arabian peninsula and linked to Salafi and Wahhabi movements. They attacked an estimated three hundred Shia internet websites including The Ahlulbayt (a.s.) Global Information Center. It was later dubbed the "largest Wahhabi hacker attack" in recent years.

However, the attack led to the retaliatory hacking of more than nine hundred Wahhabi and Salafi websites. One such successful attack was documented on video and uploaded to YouTube on 3 October 2008. The hacker, a Shia from the United Arab Emirates using the handle "ShiaZone", was shown logging into email accounts of suspected members of group-xp. The hacked email accounts reportedly yielded group-xp's contact information, information that was subsequently posted on Shia websites.

An alleged plot to assassinate Sistani was foiled on January 29, 2007, when three Jund al-Samaa gunmen were captured at a hotel near his office. It is believed to have been part of a larger attack against a number of targets in Najaf.

In May 2007, hundreds of Shias demonstrated publicly in Basra and Najaf to protest comments made by television presenter and journalist Ahmed Mansour during a Qatari broadcast of Al Jazeera television programming. While presenting Bela Hodod (a.k.a. Without Borders), Mansour voiced skepticism of al-Sistani's leadership credentials while directing questions about the Iraqi-born cleric to his guest, Shia cleric Jawad al-Khalsi. Mansour also suggested that al-Sistani was not aware of contemporary problems in Iraq or of prevailing post-war conditions, and he alleged that Sistani's edicts were, largely, written and disseminated by aides. At another point, Mansour asked Khalsi whether the United States was using Iraqi politicians, and also al-Sistani, to promote Western interests in Iraq.

He has consistently urged the Iraqi Shia not to respond in kind to attacks from Sunni Salafists, which have become common in Sunni-dominated regions of Iraq like the area known as the "Triangle of Death," south of Baghdad. Even after the destruction of the Shia Al-Askari Mosque in Samarra in February 2006, his network of clerics and preachers continued to urge calm and told their followers that "it was not their Sunni neighbors who were killing them but foreign Wahhabis." Sistani's call for unity after the bombing of the mosque helped to control a potentially dangerous situation, preventing the country to enter in a bloody sectarian war. Sistani did the same when the same mosque was bombed again in 2007.

In an online open poll, 2005, Ali al-Sistani was selected as the 30th topmost intellectual person in the world on the list of Top 100 Public Intellectuals by Prospect (UK) and Foreign Policy (US).

In early August 2004, Sistani experienced serious health complications related to a previously diagnosed heart condition. He traveled to London to receive medical treatment. It was, reportedly, the first time that Sistani had left Iraq in decades, and may have been due, in part, to growing concerns for his safety from sectarian violence. Though still recovering, Sistani returned later in the month to broker a military truce at the Imam Ali Mosque in Najaf where Muqtada al-Sadr and the Mahdi Army had been cornered by American and Iraqi forces. Sadr, who rose rapidly to prominence through a series of independent military actions beginning in 2004, has since actively challenged Sistani's more progressive influence over Shia in the region.

Sistani's edicts reportedly provided many Iraqi Shia cause for participating in the January 2005 elections—he urged, in a statement on October 1, 2004, that Iraqis recognize the election as an "important matter," additionally, Sistani asked that the elections be "free and fair ... with the participation of all Iraqis." Soon after, al-Sistani issued a fatwa alerting Shia women that they were religiously obligated to participate in the election, even if their husbands had forbidden them from voting. In an issued statement Sistani remarked that, "truly, women who go forth to the polling centers on election day are like Zaynab, who went forth to Karbala."

Shortly after the US invasion began, Sistani issued a fatwa advising Shia clergy to become engaged in politics in order to better guide the Iraqi people toward "clearer decisions," and to fight "media propaganda." As the summer of 2003 approached, Sistani and his followers began to petition the occupying forces for a constitutional convention. Later, Sistani called for a democratic vote of the people for the purpose of forming a transitional government. Observers described the move as being a path leading directly to Shia political dominance over Iraq's government, as Shia Muslims make up approximately 65% of the total Iraqi population. Subsequently, Sistani criticized plans for an Iraqi government for not being democratic enough.

During the years of Saddam Hussein's rule of Iraq through the Baath Party, al-Sistani was untouched during the violent Baathist repression and persecution that killed many clerics including Mohammad al-Sadr in 1999, for which Saddam denied any involvement. Al-Sistani's mosque was forcefully shut down in 1994 and did not reopen until the 2003 US-led invasion of Iraq.

When Khoei died in 1992, Abd al-A'la al-Sabziwari briefly became the leading marja'. However, when he died in 1993, al-Sistani ascended to the rank of Grand Ayatollah through traditional peer recognition of his scholarship. His role as successor to Khoei was symbolically cemented when he led funeral prayers for Khoei, he also inherited most of Khoei's network and following.

Al-Sistani is married to the daughter of Muhammad-Hassan al-Shirazi (d. 1972), the grandson of Mirza Shirazi. He has two sons, Muhammad-Ridha and Muhammad-Baqir.

Sistani began his religious education as a child, first in Mashhad in his father's hawzah, and continuing later in Qom. In Qom he studied under Grand Ayatollah Hossein Borujerdi. Later in 1951, Sistani traveled to Iraq to study in Najaf under Grand Ayatollah Abu al-Qasim al-Khoei. Sistani rose to the rank of mujtahid in 1960, at the age of thirty-one.

Ali al-Husayni al-Sistani (Arabic: علي الحسيني السيستاني; Persian: على حسينى سيستانى, romanized: Ali-ye Hoseyni-ye Sistāni; born 4 August 1930), commonly known as Ayatollah Sistani, is an Iranian–Iraqi Twelver Shia Ayatollah and marja'. He has been described as the spiritual leader of Shia Muslims worldwide, and one of the most senior scholars in Shia Islam. He has been included in all editions of "The Muslim 500: The World's Most Influential Muslims" mostly in the top ten positions since 2009. Sistani ranks ninth in 2023. Time magazine named him one of the 100 most influential people in the world in 2004 and 2005.

Sistani was born in either 1929 or 1930 in Mashhad, to a family of religious clerics who claim descent from Husayn ibn Ali, the grandson of Muhammad. His father was Mohammad-Baqir al-Sistani and his mother was the daughter of Ridha al-Mehrebani al-Sarabi.
