FIVE PILLARS OF ISLAM

Muslims performing salah (Islamic prayer)

Rituals of the Hajj (pilgrimage) include walking seven times around the Kaaba in Mecca.
The Five Pillars of Islam (Arabic: أركان الإسلام) are five practices essential to Sunni Islam. Shi'a Muslims subscribe to different sets of pillars which substantially overlap with the Five Pillars. They are:
The shahadah, which is the basic creed or tenet of Islam: "'ašhadu 'al-lā ilāha illā-llāhu wa 'ašhadu 'anna muħammadan rasūlu-llāh", or "I testify that there is none worthy of worship except God and I testify that Muhammad is the Messenger of God." This testament is a foundation for all other beliefs and practices in Islam. Muslims must repeat the shahadah in prayer, and non-Muslims wishing to convert to Islam are required to recite the creed.
Salah, or ritual prayer, which must be performed five times a day. Each salah is done facing towards the Kaaba in Mecca. Salah is intended to focus the mind on God, and is seen as a personal communication with him that expresses gratitude and worship. Salah is compulsory but flexibility in the specifics is allowed depending on circumstances. In many Muslim countries, reminders called Adhan (call to prayer) are broadcast publicly from local mosques at the appropriate times. The prayers are recited in the Arabic language, and consist of verses from the Qur'an.
Zakat, or alms-giving. This is the practice of giving based on accumulated wealth, and is obligatory for all Muslims who can afford it. A fixed portion is spent to help the poor or needy, and also to assist the spread of Islam. The zakat is considered a religious obligation (as opposed to voluntary charity) that the well-off owe to the needy because their wealth is seen as a "trust from God's bounty". The Qur'an and the hadith also suggest a Muslim give even more as an act of voluntary alms-giving (sadaqah).
Sawm, or fasting during the month of Ramadan. Muslims must not eat or drink (among other things) from dawn to dusk during this month, and must be mindful of other sins. The fast is to encourage a feeling of nearness to God, and during it Muslims should express their gratitude for and dependence on him, atone for their past sins, and think of the needy. Sawm is not obligatory for several groups for whom it would constitute an undue burden. For others, flexibility is allowed depending on circumstances, but missed fasts usually must be made up quickly. Some Muslim groups do not fast during Ramadan, and instead have fasts different times of the year.[

The Hajj, which is the pilgrimage during the Islamic month of Dhu al-Hijjah in the city of Mecca. Every able-bodied Muslim who can afford it must make the pilgrimage to Mecca at least once in his or her lifetime. When the pilgrim is about ten kilometers from Mecca, he must dress in Ihram clothing, which consists of two white seamless sheets. Rituals of the Hajj include walking seven times around the Kaaba, touching the Black Stone, running seven times between Mount Safa and Mount Marwah, and symbolically stoning the Devil in Mina. The pilgrim, or the hajji, is honored in his or her community, although Islamic teachers say that the Hajj should be an expression of devotion to God instead of a means to gain social standing.
