Belief in all the prophets sent by God including Noah, Abraham, Ishmael, Isaac, Jacob, Moses, Jesus and Muhammad. Although Muslims believe in Isa or Jesus they don't think of Jesus as the Son of God the way Christians do.
Belief in the Day of Judgment and life after death. The best reward for performing good deeds is getting closer to God.
Belief in divine decree. This means that God is all-powerful and nothing can happen without His permission, however, he has given human beings freedom to choose whether to be good or bad. In the end, everyone will be questioned about how they lived in this life.
Islam is a monotheistic faith centered around belief in the one God (Allah). In this regard, it shares some beliefs with Judaism and Christianity by tracing its history back to the patriarch Abraham, and ultimately to the first prophet, Adam. All the prophets preached the same universal message of belief in one God and kindness to humanity. The last in the series of prophets, according to Muslims, was Muhammad.
Shahadah (declaration of faith)—to bear witness or testify that there is no god except one God (Allah) and Muhammad is His prophet or messenger.
Salat (ritual prayer)—the five daily prayers are performed at dawn, noon, mid-afternoon, sunset and night. The prayers are offered in Arabic language and facing the direction of Mecca.
Zakah (alms tax) –Giving 2.5% of one's wealth to the poor and needy.
Sawm (fasting)—Muslims fast during the daylight hours in the ninth month of the Islamic lunar calendar called Ramadan. The purpose is to remind people of the goodness of what they have and to show equality with the poor. Ramadan is a time for study and self-discipline.
Hajj (pilgrimage): Muslims believe in making a pilgrimage to Mecca to the Ka'bah at least once in their lifetime. The kA'bah is believed to have been built by Ibrahim (Abraham) and one of his sons. Muhammad restored it to worship Allah. For this reason it is a very sacred place to Muslims.
Muslims hold that for someone to worship any other gods or deities other than Allah (Shirk (polytheism)) is a sin that will lead to separation from Allah. Muslims believe that Allah sent the Qur'an to bring peace and harmony to humanity through Islam (submission to Allah).
