The chart shows which Surah and page # a new Juz starts.
♦ It's very helpful for Quran students or readers.
♦ Quickly check which Juz you are reading.
♦ Also helpful for those who want to set pages to read daily, weekly, etc.
Please note this chart pages are for Quran Uthmani script, Othmani print:
To see if it matches your Quran, see if surah Nas end at page 604.
If it does then that's the Othmani print.
