The Ajiza (Sections) of the Quran - Index

The words of the Qur’an are primarily divided by chapter (surah) and verse (ayat). The chapters vary in length, and generally are ordered from longest to shortest.
To ease the reading process, the Qur’an is additionally divided into 30 equal sections, called a juz' (plural: ajiza). The divisions of juz' do not fall evenly along chapter lines, and often break from one section to another in the middle of a chapter. These divisions are done to make it easier for one to pace the reading over a month’s period, reading a fairly equal amount each day. This is particularly important during the month of Ramadan, when it is recommended to complete at least one full reading of the Qur’an from cover to cover.
