Ulumul Qur'an is one of the basic knowledge of Islam which has many branches. It discusses issues that are ushuli and furu'i, among the science of ushuli are makki-madani, asbabun nuzul, nasikh-mansukh, muhkam-mutasyabih and the others. The furu'i examples include adab or ethics and fadha'ilul Qur'an. This furu'i discussion is useful because there is a term for the science of perfection (kamalat) in Islam. A Qur'anic scholar from Wonosobo, KH. Muntaha Al-Hafidz has special attention in this knowledge of kamalat or perfection. He wrote a book "abharul Qur'an" or the Qur'anic ocean which discusses two major themes, namely the primacy of the Qur'an and ethics with the Qur'an. This book is studied and investigated in this thesis. So that it is known the position of the abharul Qur'an among similar books from the ulama' who first composed it, as well as the role or contribution of KH. Muntaha in that sector.
