to shave their beards and required to let them grow and keep them long according to the Taliban's liking, and to wear turbans outside their households. Communists were systematically executed. Prayer was made compulsory and those who did not respect the religious obligation after the azaan were arrested. Gambling was banned, and thieves were punished by amputating their hands or feet. In 2000, the Taliban leader Mullah Omar officially banned opium cultivation and drug trafficking in Afghanistan; the Taliban succeeded in nearly eradicating the majority of the opium production (99%) by 2001. Under the Taliban governance of Afghanistan, both drug users and dealers were severely prosecuted. The Afghan custom of bacha bazi, a form of pederastic sexual slavery and pedophilia traditionally practiced in various provinces of Afghanistan, was also forbidden under the six-year reign of the Taliban regime. Cabinet ministers and deputies were mullahs with a "madrasah education". Several of them, such as the Minister of Health and Governor of the State bank, were primarily military commanders who were ready to leave their administrative posts to fight when needed. Military reverses that trapped them behind lines or led to their deaths increased the chaos in the national administration. At the national level, "all senior Tajik, Uzbek and Hazara bureaucrats" were replaced "with Pashtuns, whether qualified or not". Consequently, the ministries "by and large ceased to function".

They did not hold elections, as their spokesman explained: They modeled their decision-making process on the Pashtun tribal council (jirga), together with what they believed to be the early Islamic model. Discussion was followed by a building of a consensus by the "believers". Before capturing Kabul, there was talk of stepping aside once a government of "good Muslims" took power, and law and order were restored. As the Taliban's power grew, decisions were made by Mullah Omar without consulting the jirga and without consulting other parts of the country. One such instance is the rejection of Loya Jirga decision about expulsion of Osama bin Laden. Mullah Omar visited the capital, Kabul, only twice while in power. Instead of an election, their leader's legitimacy came from an oath of allegiance ("Bay'ah"), in imitation of the Prophet and the first four Caliphs. On 4 April 1996, Mullah Omar had "the Cloak of Muhammad" taken from its shrine, Kirka Sharif,
