(Arabic: مسلم; /English pronunciation: /MUZ-lim) is an adherent of the religion of Islam. Literally, the word means "one who submits (to God) Allah <br /><br />The Qur'an describes many Biblical prophets and messengers as Muslim: Adam, Noah (Arabic: Nuh), Moses and Jesus may peace be upon all of them and his apostles. The Qur'an states that these men were Muslims because they submitted to God, preached his message and upheld his values. Thus, in Surah 3:52 of the Qur'an, Jesus’ disciples tell Jesus, "We believe in God; and you be our witness that we submit and obey (wa ashahadu bil-muslimūna)." <br /><br />Muslims consider making ritual prayer five times a day a religious duty (fard) (see the section on Ismāˤīlīs below for exceptions); these five prayers are known as fajr, dhuhr, ˤasr, maghrib and ˤishā'. There is also a special Friday prayer called jumuˤah. Currently, the most up to date reports from an American think-tank and PBS have estimated 1.2 to 1.57 billion Muslims populate the world, or about 25% of an estimated 2009 world population of 6.8 billion,with 60% in Asia and 20% of Muslims living in the Middle East and North Africa. <br /><br />The majority of Muslims accept as a Muslim anyone who has publicly pronounced the Shahadah (declaration of faith) which states, <br /><br />Ash-hadu an laa ilaha illa-lah <br />Wa ash-hadu anna Muhammadan rasulullah <br />"I bear witness there is no deity worthy of worship except Allah and I bear witness, Muhammad is His messenger".
