Prayer (Salah), in the sense of worship, is the second pillar of Islam. Prayer is obligatory and must be performed five times a day. These five times are dawn (Fajr), immediately after noon (Dhuhr), mid-afternoon ('Asr), sunset (Maghrib), and early night (Isha').
Sawm (Fasting), the fourth pillar of Islam, is another act of Ibadah. All adult Muslims must fast from dawn to sunset every day of Ramadan, the ninth month of the Islamic calendar. This means abstaining from eating, drinking, smoking and conjugal relations during the hours of fasting. Travellers and the sick can defer fasting during Ramadan and make up for it later.
They are the framework of the Muslim life: faith, prayer, concern for the needy, self-purification, and the pilgrimage to Makkah for those who are able.
