Which of the following is not a teaching of Islam?

• A. Hajj at least once every ten years.
• B. Five Pillars of Islam
• C. Belief in Allah and His prophets
• D. Judgment Day and accountability

Answer: (A)

Hajj is a pillar of Islam, and it is required once in a lifetime for Muslims who are physically and financially able. The idea that it must be performed at least once every ten years is not accurate. Hajj is a once-in-a-lifetime obligation, not a recurring duty every decade.

The other statements reflect genuine aspects of Islamic teaching: the Five Pillars outline the core practices of worship and conduct, belief in Allah and His prophets is the central creed, and the Day of Judgment and accountability is a fundamental belief about what happens after life. Because the frequency of Hajj is misstated, that statement does not fit as a teaching.
