Concept:The term used in Islam for a person who has memorized the entire Qur'an is called a Hafiz.
Explanation:Hafiz is an Arabic word meaning "one who preserves" or "one who memorizes."
It is specifically given to a Muslim who has memorized the entire Qur'an accurately.
The Qur'an is a very long book, yet a Hafiz commits all of its verses to memory.
Qadi means an Islamic judge, Qari means a person who recites the Qur'an, and Katib means a writer or scribe.
None of these three terms refers to memorization of the whole Qur'an.
Therefore, the correct term for a memorizer of the Qur'an is Hafiz.
Answer:Option D: Haftz (Hafiz)
