]Allah - Who is Allah?
Muslims believe that Allah alone is the Lord, the Creator and the Provider of the entire universe. Muslims also believe that Allah alone, and no one else, is worthy of worship. The primary Islamic belief is that "There is no one worthy of worship other than Allah and Muhammad is his messenger".
Allah says in the Quran (interpretation of the meaning):
“He is the Originator of the heavens and the earth. How can He have children when He has no wife? He created all things and He is the All-Knower of everything.
Such is Allah, your Lord! None has the right to be worshipped but He, the Creator of all things. So worship Him (Alone), and He is the Wakeel (Trustee, Disposer of affairs or Guardian) over all things”[Al-Anaam 6:101-102]
Allah has 99 names that reflect His attributes. Muslims believe that Allah revealed all holy books such as the Torah, Bible (Injeel) and the Final word of God (Allah), called the Quran. Allah revealed the Quran in 23 years over prophet Muhammad (peace be upon him).
Muslims also believe (through Allah's revelation on his messengers) that Moses, Jesus, and Muhammad were all His prophets and messengers. They were regular human beings and while Allah did bestow upon them the ability to demonstrate certain limited miracles, they were only His Messengers
