The Quran in general is divided into chapters (surah) and verses (ayat). It is additionally divided into 30 equal sections, called juz . Of note, division into Juzʾ has no relevance to the meaning of the Quran and anyone can start reading from anywhere in the Quran. The divisions of juz do not fall evenly along chapter lines. These divisions make it easier 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 Quran from cover to cover. Some use this divisions to facilitate recitation of the Quran in a month, especially during Ramadan when the entire Quran is recited in the Tarawih prayers, reciting approximately one juzʾ a night. 

The fifteenth juz’ of the Quran contains one complete chapter of the Quran (Surah Al-Isra, also known as Bani Isra'il), and part of the next chapter (Surah Al-Kahf), marked as 17:1-18:74.
