Islam

Qur'an - literally meaning "the recitation", is the central religious text of Islam, which Muslims believe to be a revelation from God. Quranic chapters are called suras and verses are called ayahs.

Hadith - in Muslim religious use is often translated as prophetic 'traditions', meaning the corpus of the reports of the teachings, deeds and sayings of the Islamic prophet Muhammad. The hadith literature was compiled from oral reports that were in circulation in society around the time of their compilation long after the death of Muhammad. Bukhari's collection is considered the most reliable by many traditional religious scholars who are Sunnis. The Shi'as believe in an entirely separate body of Hadith.

Tafsir - is the Arabic word for exegesis, usually of the Qur'an. In Islamic contexts, it is defined as understanding and uncovering the Will of Allah which has been conveyed by the Qur'anic text, by means of the Arabic language and one's own knowledge.

Surah (also spelled Surat, Sura) - is a chapter of the Qur'an. There are 114 chapters of the Qur'an, each divided into verses.
