Teachings
Islam

Islam is a monotheistic religion. They believe in one god, Allah. They encourage alms giving, giving to the unfortunate. They believe in heaven and hell and one life before it. If you did something bad, then you're in hell. But if you did something good, then you go to heaven. In Islam, the teachings are taught by Kalifahs and their holy book, the Qu'ran (Koran).
Hinduism

Hinduism is a polytheistic religion.. They believe in a god in millions of different forms, Vishnu. Unlike Islam, they strongly discourage alms giving, because they believe that the unfortunate deserve to be there, because they did something in their previous life. Hindus, unlike Muslims, believe that you reincarnate, or reborn, over and over again until you have finally reached salvation, or mastering of the Hindu teachings. In Hinduism, their teachings are taught by Gurus and their holy book, the Vedas.
