"It is important in this context to remember that Islam is not based on original sin but that nevertheless it does accept the fall of man (alhubut) from the primordial and original state of perfection in which he was created. According to Islam, the great sin of man is in fact forgetfulness (al-ghaflah) and the purpose of the message of revelation is to enable man to remember. That is why one of the names of the Quran itself is "the Remembrance of Allah" (dhikr Allah) and why the ultimate end and purpose of all Islamic rites and of all Islamic conjunctions is the remembrance of Allah."
