Concept:Tafsir is the discipline of explaining and clarifying the meanings of Qur'anic verses.
Explanation:Clarification of Qur'anic verses means interpreting and explaining their correct meanings.
The word Tafsir comes from the Arabic root "fassara," which means to explain, expound, or interpret.
Tafsir provides context, background, and detailed commentary so that the verses are understood clearly according to God's will.
A scholar who writes or delivers Tafsir is called a mufassir.
The other options are not correct: Qira'ah refers to the different modes of reciting the Qur'an.
Ijthad means independent reasoning used by scholars in Islamic jurisprudence, not explanation of the Qur'an.
Tahil is not the recognized Islamic term for Qur'anic interpretation; the proper and standard term for this function is Tafsir.
Therefore, clarifying and explaining the verses of the Qur'an is achieved through Tafsir.
