The Quran is the holy book of Islam, and Muslims around the world consider it a sacred text. Reciting the Quran is an essential part of Islamic worship, and many Muslims strive to recite it beautifully and with proper Tajwid (rules of recitation). Osama bin Laden, who was born into a wealthy Saudi Arabian family, was raised in a devout Muslim household and was known to be well-versed in the Quran.
