Ibn Umar, may Allah be pleased with him, relates that the Holy Prophet, peace and blessings of Allah be upon him, said: "Islam is based on five articles: 
  
1. To bear witness that there is none worthy of worship save Allah and that Muhammad (peace and blessings of Allah be upon him) is the Messenger of Allah. 

Zakat (Alms giving) is a part of devotion enjoined upon Muslims by the Holy Quran. It is a means where the well-off pay a set amount of their wealth. Zakat means to purify oneself. It is obligatory on Muslims to pay a little percentage of their accumulated wealth towards Zakat, which is used for the benefit of the needy and the poor. Zakat is not levied on one's property that is in personal use, rather on the assets which have a means of increasing and which are surplus to one's needs. It is a means of social justice and order. It teaches sympathy of the highest order.

Along with salat, another important form of worship is fasting. It is obligatory for each Muslim, apart from some exemptions, to fast in the month of Ramadhan. During the hours of fasting, food and drink and conjugal relations between husband and wife are forbidden. It is enjoined that during fasting one should pay attention to remembrance of God and study the Holy Quran in abundance. One should try to curtail one's worldly pastimes as much as possible during Ramadhan, and to be particularly inclined towards charity and alms giving.  

Salat is one of the five pillars of Islam, it is a most important constituent of the faith. It is prayer of a very high level. The Holy Quran repeatedly enjoins the offering of salat and indeed declares it to be a fundamental trait of a believer. The benefits of salat are countless. The Holy Quran says: 

"And enjoin Prayer on thy people, and be constant therein. We ask thee not for provision; it is We that provide for thee. And the end is for the righteous".  

Hajj is the fifth Pillar of Islam and another form of worship. It is an annual pilgrimage to the holy sites in Mecca which each adult Muslim, who can afford it, has to perform once in life time. Apart from the financial aspect, the ability to afford the pilgrimage also means that one is able to travel and perform the Hajj in peace. 

A Muslim expresses his/her faith (Iman) in the following words: 
Ash-hadu anla ilaha illal-Lahu Wahdahu la Sharika Lahu wa-ash-hadu anna Muhammadan abduhu wa rasuluhu 
  
The English translation of the Shahadah is as follows: 
I bear witness that there is none worthy of worship except Allah, the One, without any partner. And I bear witness that Muhammad is His servant and His Messenger.
