Final answer:
False, Following the six articles of faith is not the most important duty for Muslims; rather, adhering to the five pillars of Islam is considered the foundational practice of the Islamic faith.
Step-by-step explanation:
The statement that for Muslims, following the six articles of faith is the most important duty is false. For Muslims, the five pillars of Islam represent the foundation and most important practices of their faith. These pillars are: Shahadah (the declaration of faith), Salat (prayer five times a day), Sawm Ramadan (fasting during the month of Ramadan), Zakat (giving to charity), and the Hajj (the pilgrimage to the holy city of Mecca).
