Background: According to most sources, Omar was born sometime between 1950 and 1962 in a village in Kandahar Province, Kingdom of Afghanistan (in present-day Kandahar Province or Uruzgan Province). Some suggest his birth year as 1950 or 1953, or as late as around 1966. According to a "surprise biography" published by the Taliban in April 2015, he was born in 1960. His exact place of birth is also uncertain; one possibility is a village called Nodeh near the city of Kandahar.
Context: On 4 April 1996, supporters of Mullah Omar bestowed on him the title Amir al-Mu'minin ('myr lmw'mnyn, "Commander of the Faithful"), after he donned a cloak alleged to be that of Muhammad that was locked in a series of chests, held inside the Shrine of the Cloak in the city of Kandahar. Legend decreed that whoever could retrieve the cloak from the chest would be the great Leader of the Muslims, or "Amir al-Mu'minin".  In September 1996, Kabul fell to Mullah Omar and his followers. The civil war continued in the northeast corner of the country, near Tajikistan. The nation was named the Islamic Emirate of Afghanistan in October 1997 and was recognized by Pakistan, Saudi Arabia and the United Arab Emirates. Described as a "reclusive, pious and frugal" leader, Omar very seldom left his residence in the city of Kandahar, and visited Kabul only twice between 1996 and 2001 during his tenure as ruler of Afghanistan. In November 2001, during a radio interview with the BBC, Omar stated: "All Taliban are moderate. There are two things: extremism ['ifraat', or doing something to excess] and conservatism ['tafreet', or doing something insufficiently]. So in that sense, we are all moderates - taking the middle path."  According to Pakistani journalist Rahimullah Yusufzai, Mullah Omar stated in the late 1990s, "We have told Osama [Bin Laden] not to use Afghan soil to carry out political activities as it creates unnecessary confusion about Taliban objectives."  In 1998, despite receiving a personal invitation from Saudi Arabia's ruler, King Fahd, Omar refused to make a pilgrimage to Mecca and wouldn't do one in his lifetime.  Mullah Omar was also "Head of the Supreme Council of Afghanistan".  In July 1999, Mullah Mohammed Omar issued a decree in favor of the preservation of the Bamiyan Buddha statues. Because Afghanistan's Buddhist population no longer exists, so the statues are no longer worshiped, he added: "The government considers the Bamiyan statues as an example of a potential major source of income for Afghanistan from international visitors. The Taliban states that Bamiyan shall not be destroyed but protected."  In early 2000, local Taliban authorities asked for UN assistance to rebuild drainage ditches around tops of the alcoves where the Buddhas were set.  In March 2001, the Buddhas of Bamiyan were destroyed by the Taliban under an edict issued from Mullah Omar, stating: "all the statues around Afghanistan must be destroyed." This prompted an international outcry. Information and Culture Minister Qadratullah Jamal told Associated Press of a decision by 400 religious clerics from across Afghanistan declaring the Buddhist statues against the tenets of Islam. "They came out with a consensus that the statues were against Islam," said Jamal. A statement issued by the ministry of religious affairs of the Taliban regime justified the destruction as being in accordance with Islamic law. The then Taliban ambassador to Pakistan Abdul Salam Zaeef held that the destruction of the Buddhas was finally ordered by Abdul Wali, the Minister for the Propagation of Virtue and the Prevention of Vice.  The Taliban supreme leader Mullah Omar explained why he ordered the statues to be destroyed in an interview:  I did not want to destroy the Bamiyan Buddha. In fact, some foreigners came to me and said they would like to conduct the repair work of the Bamiyan Buddha that had been slightly damaged due to rains. This shocked me. I thought, these callous people have no regard for thousands of living human beings - the Afghans who are dying of hunger, but they are so concerned about non-living objects like the Buddha. This was extremely deplorable. That is why I ordered its destruction. Had they come for humanitarian work, I would have never ordered the Buddha's destruction.
