For the convenience of those who wish to read all the surahs of this great book over a fixed period, the Glorious Qur'an is divided into 30 equal parts, each called one juz' (plural, ajza' meaning parts), or into seven equal segments, each called a manzil. Each juz' is subdivided into two hizbs (sections) which are further divided in four rubs (quarters). Therefore, if one reads one rub every night, the entire Qur'an will be read in about eight months. Similarly, if one wishes to read the complete Qur'an in one week, one must read one manzil a day. Large surahs of the Glorious Qur'an are also divided into rukuc according to the meaning of the passage. The Noble Qur'an has been well preserved in its original form throughout fourteen centuries in two ways: 1) in writing, and 2) by memorising and passing the words from the heart of one generation into that of another. Two copies of the original standard Qur'an still exist today, one in Istanbul  (Turkey) and one in Tashkent  (Uzbekistan). The Glorious Qur'an is considered to be so Holy that Muslims treat it with enormous respect. While It is being read:
• You must not speak
• You must not eat or drink
• You must concentrate quietly.
It is not to be touched unnecessarily. Before reading it or touching it: • You must wash thoroughly • You must be in the right frame of mind and have good intentions • You must seek refuge in God from satan's wicked intentions • Women should be clear from menstruation. Upon completion of its recitation one should conclude the session with certain phrases, at least stating that the Exalted God speaks the Truth, His Blessings be upon Muhammad (SA) and his kinsfolk. But normally, a longer prayer is recited. When not being recited, it should be: • Placed high up, so that nothing is put on top of it • Kept covered with a light cloth to shield it from dust. I shall refrain from describing this unique Book of Divine Guidance in my own humble words and examine how the Great Qur'an Itself defines Its own aspects.
