ALLAH

Islam's fundamental theological concept is tawhīd—the belief that there is only one god. The Arabic term for God is Allāh; most scholars believe it was derived from a contraction of the words al- (the) and ʾilāh (deity, masculine form), meaning "the god" (al-ilāh), but others trace its origin to the Aramaic Alāhā. The first of the Five Pillars of Islam, tawhīd is expressed in the shahadah (testification), which declares that there is no god but God, and that Muhammad is God's messenger. In traditional Islamic theology, God is beyond all comprehension; Muslims are not expected to visualize God but to worship and adore him as a protector. God is described in a chapter (sura) of the Qur'an as "…God, the One and Only; God, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him."Muslims consider the Qur'an to be the literal word of God; it is the central religious text of Islam.^[25] Muslims believe that the verses of the Qur'an were revealed to Muhammad by God through the angel Gabriel on many occasions between 610 and his death on June 8, 632. The Qur'an was reportedly written down by Muhammad's companions (sahabah) while he was alive, although the prime method of transmission was orally. The Qur'an is divided into 114 suras, or chapters, which combined, contain 6,236 āyāt, or verses. The chronologically earlier suras, revealed at Mecca, are primarily concerned with ethical and spiritual topics. The later Medinan suras mostly discuss social and moral issues relevant to the Muslim community. The Qur'an is more concerned with moral guidance than legal instruction, and is considered the "sourcebook of Islamic principles and values".

Belief in angels is crucial to the faith of Islam. The Arabic word for Angels (malak) means "messenger", like its counterparts in Hebrew (malakh) and Greek (angelos). According to the Qur'an, angels do not possess free will, and worship God in perfect obedience.^[31] Angels' duties include communicating revelations from God, glorifying God, recording every person's actions, and taking a person's soul at the time of death. They are also thought to intercede on man's behalf. The Qur'an describes angels as "messengers with wings—two, or three, or four (pairs): He [God] adds to Creation as He pleases…"

Belief in the "Day of Resurrection", yawm al-Qiyāmah (also known as yawm ad-dīn, "Day of Judgment" and as-sā`a, "the Last Hour") is also crucial for Muslims. They believe that the time of Qiyāmah is preordained by God but unknown to man. The trials and tribulations preceding and during the Qiyāmah are described in the Qur'an and the hadith, and also in the commentaries of Islamic scholars. The Qur'an emphasizes bodily resurrection, a break from the pre-Islamic Arabian understanding of death. It states that resurrection will be followed by the gathering of mankind, culminating in their judgment by God.
