Final answer:
During Ramadan, Muslims must fast from dawn to dusk, abstaining from food and drink. This fulfills one of the Five Pillars of Islam, which also includes the declaration of faith, prayer, charity, and if possible, the pilgrimage to Mecca. (option a)
Step-by-step explanation:
During the Ramadan, Muslims are required to go without food or drink from dawn to dusk. This practice is known as fasting and is one of the Five Pillars of Islam, the foundational framework of a Muslim's faith and practice. Fasting during Ramadan commemorates the month during which the first revelations of the Quran were made to the Prophet Muhammad. It's a time dedicated to prayer, reflection, and community.
Aside from fasting, the Five Pillars also include Shahadah (declaration of faith), Salat (praying five times a day), Zakat (giving to charity), and Hajj (the pilgrimage to Mecca). Fulfilling these pillars is a way for Muslims to show their faith and practice the religion of Islam. The pilgrimage to Mecca, or Hajj, is another significant religious duty that each Muslim aspires to undertake at least once in their lifetime, if they are able to do so.
Hence, the answer is option a.
