The Holy Qur'an for Kids - Juz 'Amma - Amma for School Children - Part 30

The main division of the Qur'an is into chapter (surah) and verse (ayat). The Quran is additionally divided into 30 equal sections, called juz' (plural: ajiza). The 30th juz' of the Quran includes the last 36 surahs (chapters) of the holy book, from the first verse of the 78th chapter (An-Nabaa 78:1) and continuing to the end of the Quran, or verse 6 of the 114th chapter (An-Nas 114:1).

This entire juz' has a special name and a special place in Islamic practice. This juz' is often called juz' amma, a name which reflects the first word of the first verse of this section (78:1). It is usually the first part of the Quran that children and new Muslims learn to read, although it comes at the end of the Quran. This is because the chapters are shorter and easier to read/grasp, and the messages revealed in this section are most fundamental to a Muslim's faith.

"Whenever some people gather in one of Allah's houses to recite the book of Allah and study it among themselves - then calmness (tranquillity) descends upon them, the angels surround them, mercy covers them, and Allah mentions them to those who are with Him." 

The Prophet (sallallhu 'alayhi wa sallam), Sahh Muslim.
