Islam
Islam is an Abrahamic religion based on the Quran and the teachings of Muhammad. The monotheistic religion has an estimated 2 billion worldwide adherents, called Muslims. Islam is the world's second-largest religious population after Christianity. Muslims believe that there is a primordial faith that was revealed many times through earlier prophets and messengers, including Adam, Noah, Abraham, Moses, and Jesus, and they believe that Islam is the universal and complete version of this faith. Muslims consider the Quran to be the verbatim word of God and the unaltered, final revelation. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (Torah), the Zabur (Psalms), and the Injil (Gospel). They believe that Muhammad is the main and final of God's prophets, through whom the religion was completed, and after whom no new prophet or divine law will come. The teachings and normative examples of Muhammad, called the Sunnah, documented in accounts called hadith, provide a constitutional model for Muslims. Islam is based on the belief in the oneness and uniqueness of God (tawhid), and belief in an afterlife (akhirah) with the Last Judgment—wherein the righteous will be rewarded in paradise (jannah) and the unrighteous will be punished in hell (jahannam). The Five Pillars, considered obligatory acts of worship, are the Islamic oath and creed (shahada), daily prayers (salah), almsgiving (zakat), fasting (sawm) in the month of Ramadan, and a pilgrimage
