The five pillars of faith are duties each Muslim performs to demonstrate his or her faith.
1. Testimony of Faith (Kalima)
One must state, "There is no god, but Allah, and Muhammad is the Prophet of Allah." It consists of three parts
a) To reject all the false gods.
b) To accept Allah as the only sole creator of everything.
c) To Mohammad as the last messenger of Allah.
Quran declares, "Say: He is Allah, the One and Only! Allah, the Eternal, Absolute; He begetteth not nor is He begotten. And there is none like unto Him. "
2. Prayer (Salat)
It is compulsory for every Muslim to pray five times a day at respective timings facing towards the direction of Mecca. During the prayer, Muslims narrate verses from the Holy Quran, specially the following prayer which is recited at least 17 time a day,
"All praise is due to Allah, Lord of the worlds, The Most Gracious, the Most Merciful, and Sovereign of the Day of Judgment. It is You alone we worship and You alone we ask for help. Guide us to the straight path; The path of those upon whom You have bestowed favor, not of those who have evoked Your anger or of those who are astray." (1:1-7)
Quran tells about those who will get eternal success by stating that, "Certainly will the believers have succeeded, they who are during their prayer humbly submissive" (23:1-2)
3. Almsgiving (Zakat)
The word Zakat means "to grow" or "to purify". It literally means to gain Allah�s blessings and purify the wealth by helping the needy. It is mandatory on every Muslim to give 2.5% of their yearly savings (or excess money) for charity.
Quran emphasizes the importance of zakat on various occasions, "Alms are for the poor and the needy, and those employed to administer the (funds); for those whose hearts have been (recently) reconciled (to Truth); for those in bondage and in debt; in the cause of Allah. and for the wayfarer: (thus is it) ordained by Allah, and Allah is full of knowledge and wisdom." (9:60)
4. Fasting (Sawm)
Following zakat, every Muslim is required to fast during the month of Ramadan from sunrise to sunset. During this period, Muslims are forbidden to eat, drink, smoke or have an intercourse. It not only physical discipline in one�s life, but it is also a way to feel the afflictions of the poor.
Quranic verses explain fasting in detail,
"O ye who believe! Fasting is prescribed to you as it was prescribed to those before you, that ye may (learn) self-restraint" (2:183)
"Ramadhan is the (month) in which was sent down the Qur'an, as a guide to mankind, also clear (Signs) for guidance and judgment (Between right and wrong). So every one of you who is present (at his home) during that month should spend it in fasting, but if any one is ill, or on a journey, the prescribed period (Should be made up) by days later. Allah intends every facility for you; He does not want to put to difficulties. (He wants you) to complete the prescribed period, and to glorify Him in that He has guided you; and perchance ye shall be grateful." (2:185)
5. Pilgrimage (Hajj)
Hajj literally means to "set out for place". For Muslim, it is a pilgrimage to Kaaba (House of Allah) in Makkah. It is the responsibility of every physically and financially able Muslim to perform this offering at least once in a lifetime. Hajj is performed on the 10th day of Dhu al-Hijjah (the 12th and the final month of the Islamic calendar). Hajj is the symbol of unity among the Muslims. Millions of believers from all over the world participate in the ritual irrespective of their caste, color, creed or tradition. It tears down the difference of social status and brings all the Muslims on one platform. During this occasion, men only wear two unstitched clothes; one covers the lower part, and the other is wrapped around the shoulders. Women wear simple white dress and headscarf.
Allah says in the Holy Quran, "For Hajj are the months well known. If any one undertakes that duty therein, Let there be no obscenity, nor wickedness, nor wrangling in the Hajj. And whatever good ye do, (be sure) Allah knoweth it. And take a provision (With you) for the journey, but the best of provisions is right conduct. So fear Me, o ye that are wise." (2:197)
