“O ye who believe! Fasting is prescribed to you as it was prescribed to those before you, that ye may (learn) self-restraint, (Fasting) for a fixed number of days; but if any of you is ill, or on a journey, the prescribed number (should be made up) from days later.
Another exceptionally remarkable institution and major pillar of Islam is the Zakah. To the Qur’anic word Zakah and the meaning it conveys, there is no equivalent in any other language as far as we known.
The final pillar and one of the finest institutions of Islam is the Hajj or pilgrimage to Mecca. The performance of the Hajj is obligatory, at least once in a lifetime, upon every Muslim, male or female, who is mentally, financially and physically fit. The Muslim who is of responsible age, in fairly good health, and is financially capable and secure must make the Hajj at least once in his or her lifetime.
For a convert, the first step to enter Islam is to say "ash.hado an la ilaha illa Allah, wa ash.hado anna Mohammadan rasoolo Allah" which is best translated to: I bear witness that there is no deity except God, and that Mohammed is a messenger of God. God in Arabic means Allah; it is the name of God, as Arabs say.
