Islam is based on 5 pillars :

1.     Shahada

2.     Salat

3.     Zakat

4.     Siyam

5.     Hajj

These will be explained later. Some of the additional practices Muslims are required to observe include Modesty, Kindness to neighbors, Cleanliness, Justice, Close family ties and Facing the direction of the Ka'ba during Salat. Some of the practices which are forbidden to Muslims include Eating pork or pork by-products, Consuming alcoholic beverages, Incest and Riba, which is dealing with usury. It should be noted that a prohibition in Islam requires totally avoiding any association with the prohibited item. For example, the prohibition of alcohol means it is not allowed to drink it, transport it, buy it, sell it, manufacture it, grow the raw materials for producing it or in any way being involved with it.

The Muslim calendar is called the Hijra Calendar and is a lunar based calendar. It consists of 12 months, with each month beginning upon the sighting of the new moon. This results in months that are 29 or 30 days long. (No month can be longer than 30 days.) Hence the Hijra calendar seems to float or span through the Gregorian Calendar. The calendar gets its name from the Hijra (migration) of the Prophet Muhammad, salla ALLAHu alaihi wa sallam, from Makkah to Madina.
