According to Muslims, who is Allah?

Answer 1

Updated Answer

Allah is the God name in Arabic. He is the one and only one God that Muslims believe in. He is the creator of you and me and all mankind. He is the creator of the universe, the skies and the earth and what are in between and what is under the ground. He is the God who will judge, on the day of Judgment: who believed in God and his oneness to be of the paradise dwellers, with His will and mercy, and who don't to be the Hell dwellers except who He forgive. Muslims don't worship a person. Even prophet Mohamed, to whom God revealed the Quran as the holy book of Muslims, Muslims don't worship him. He is human that God has chosen for his mission. He also worshiped Allah as all believers in God oneness.

Allah, the God that Muslims worship, is the same God of all prophets, including Noah, Abraham, Moses, Jesus, and Mohamed. The same God that all prophets, since the start of mankind, called their people to worship, the one and only one God.
