Allah is the only god according to Islam. Allah has no gender, although is referred to as "he" in the Quran since all words are masculine or feminine. Allah is in control of everything and everyone follows the rules of nature set by Allah. Worship of Allah involves believing in him, worshipping him through acts like prayer, remembering him, and avoiding forbidden acts. Gaining knowledge is important as it leads to purification of the soul and helps one follow the right path, with learning the 99 names of Allah leading to entrance to heaven. True happiness comes from knowing Allah, not from things like music or movies, since understanding Allah is essential to a Muslim's life.
