Input: Consider Input: Passage: The Quran describes itself as "the discernment" (al-furqan), "the mother book" (umm al-kitab), "the guide" (huda), "the wisdom" (hikmah), "the remembrance" (dhikr) and "the revelation" (tanzil; something sent down, signifying the descent of an object from a higher place to lower place). Another term is al-kitab (The Book), though it is also used in the Arabic language for other scriptures, such as the Torah and the Gospels. The adjective of "Quran" has multiple transliterations including "quranic", "koranic", and "qur'anic", or capitalised as "Qur'anic", "Koranic", and "Quranic". The term mus'haf ('written work') is often used to refer to particular Quranic manuscripts but is also used in the Quran to identify earlier revealed books. Other transliterations of "Quran" include "al-Coran", "Coran", "Kuran", and "al-Qur'an".

Output: Which term meaning "the mother book" doesn't the Quran apply to itself?
