Muslims believe in the Only God, the Sole Creator, Cherisher and Sustainer of the universe and everything in it. He is truly Unique and has no partners or family.
Muslims believe that God created everything and He Himself is Uncreated. He was there before anything existed and He will be there when everything will cease to exist by His Will.
God has complete knowledge of everything in the universe and has absolute control over everything that happens anywhere in it.
Nothing is hidden from Him. He knows everything that anyone thinks or does.
He cares about His creations and is always close to them.

Muslims usually call God by the name of Allah, the Arabic word for God.
The Arabic word Allah has neither any gender nor plural and is most suitable to describe God. He is the same God that the Christians and the Jews worship.
Arab Christians and Jews also use the word Allah for God.

God will judge us all for our deeds in this world on the Day of Judgment. He is the Most Just Judge. He will reward us for even the smallest of our nice deeds and punish us for our deliberate mistakes. He is the Most Compassionate, Most Kind and Most Merciful and may forgive our mistakes if we sincerely repent. There is only one sin that He will never forgive: Taking partners with Him.
