There will be a day of judgment and humanity will be divided between the eternal destinations of Paradise and Hell. The also believe in one God that they call Allah. Allah means God.
In Hinduism, there is not just one purpose of human life, but four: Dharma - fulfilling one's purpose; Artha - prosperity; Kama - desire, sexuality, enjoyment; and Moksha - enlightenment. They believe in multiple gods.
