He founded Al-Qaeda in 1988

Asserting that the Quran prevents non-Muslims from entering the Arabian Peninsula and two of Islam's holiest temples, Bin Laden publicly criticized Saudi Arabia's reliance on US soldiers. Only Muslims should defend religion, Mecca, and Medina, the places where the Prophet Muhammad heard and read the message of Allah. Senior clerics in Saudi Arabia rebuffed Bin Laden's request to release sanctions denouncing the US military deployment because of concern for their safety. They tried to suppress Bin Laden because of his criticism of the Saudi government. The US 82nd Airborne Division was stationed in the desert only 400 kilometers from Medina after landing in the city of Dhahran in northeastern Saudi Arabia.

Ali Mohamed's al-Qaeda associate El Sayyid Nosair's New Jersey residence was raided by the FBI on November 8, 1990. They find proof of a terrorist conspiracy, including a scheme to blow up skyscrapers in New York City. This is the first instance outside of Muslim countries that al-terrorist Qaeda's preparations have been uncovered. Many people offered their assistance to Bin Laden.

Bin Laden and Abdullah Azzam established Al-Qaeda due to the sizable number of volunteer warriors they were able to assemble during the Soviet-Afghan conflict. It is a group of Islamist militants that advocate the toppling of corrupt Muslim regimes with money and force while opposing any Western presence in the Arab world. The 9/11 assaults, a string of bombs at various embassies, and strikes on US troops stationed abroad are all the work of Al-Qaeda.
