The word zakah means both "purification" and "growth." Our possessions are purified by setting aside a proportion for those in need and for the society in general.Each Muslim calculates his or her own zakah individually. This involves the annual payment of a fortieth of one's capital, excluding such items as primary residence, car and professional tools.

An individual may also give as much as he or she pleases as sadaqa-h, and does so preferably in secret. Although this word can be translated as "voluntary charity" it has a wider meaning.
The Prophet said, "Even meeting your brother with a cheerful face is an act of charity." The Prophet also said: "Charity is a necessity for every Muslim." He was asked: "What if a person has nothing?" The Prophet replied: "He should work with his own hands for his benefit and then give something out of such earnings in charity." The Companions of the Prophet asked: "What if he is not able to work?" The Prophet said: "He should help the poor and needy." The Companions further asked: "What if he cannot do even that?" The Prophet said: "He should urge others to do good." The Companions said: "What if he lacks that also?" The Prophet said: "He should check himself from doing evil. That is also an act of charity."
FASTING
Every year in the month of Ramada-n, all Muslims fast from dawn until sundown--abstaining from food, drink, and sexual relations with their spouses.

Those who are sick, elderly, or on a journey, and women who are menstruating, pregnant or nursing, are permitted to break the fast and make up an equal number of days later in the year if they are healthy and able. Children begin to fast (and to observe prayers) from puberty, although many start earlier.

Fasting is mainly a method of self-purification and self-restraint. By cutting worldy comforts, one can focue more on God. God states in the Qur'an: "O you who believe! Fasting is prescribed for you as it was prescribed to those before you that you may learn self-restraint." (Qur'an 2:183)

PILGRIMAGE
The pilgrimage to Makkah (the hajj) is an obligation only for those who are physically and financially able to do so. The annual hajj begins in the twelfth month of the Islamic year (which is lunar, not solar, so that hajj and Ramada-n fall sometimes in summer, sometimes in winter). Pilgrims wear special clothes: simple garments that strip away distinctions of class and culture, so that all stand equal before God.

The rites of the hajj, which are of Abrahamic origin, include going around the Ka'bah seven times, and going seven times between the hills of Safa and Marwa as did Hagar (Hajir, Abraham's wife) during her search for water. The pilgrims later stand together on the wide plains of 'Arafat (a large expanse of desert outside Makkah) and join in prayer for God's forgiveness, in what is often thought as a preview of the Day of Judgment.

The close of the hajj is marked by a festival, the 'Id al Adha, which is celebrated with prayers and the exchange of gifts in Muslim communities everywhere. This and the 'Id al Fitr, a festive day celebrating the end of Ramada-n, are the two holidays of the Islamic calendar.
