Tafsir

Tafsir (تفسير‎, tafsīr, "interpretation") is the Arabic word for exegesis or commentary, usually of the Qur'an. An author of tafsīr is a mufassir مفسر. The tafsir of the Qur'an as a collective, in all of their various forms, constitute one of the essential pieces of Islamic religious teaching and practice,

One of the most respected and widely used tafsir is that of ibn Kathir, which uses hadith to explain the meanings of Qur'an verses (as the Qur'an is largely without context).
