Juz' Amma is the last of thirty equally divided sections of the Qur'an, and is comprised of its final 36 chapters (Surah 78 to Surah 114). Juz' Amma is named after its very first word ('amma / عمّ), and is the most popularly memorized section of the Qur'an due to its brief chapters and concise verses. This juz' was almost entirely revealed during the Prophet's ﷺ years in Mecca, and hence its narrative focuses on centralizing the Divine in the hearts of the believers, attaching their hearts to the events of the Last Day, and ingraining in them perseverance through trials and excellence of character.This commentary on Juz' Amma was transcribed then translated from the audio recordings of the late scholar and jurist, Shaykh Muhammad Salih al-'Uthaymeen. Its clear language and intertexual method (explaining the Qur'an with other Qur'anic passages) makes it an ideal resource for anyone seeking to better comprehend what they recite in prayer, develop their Qur'anic vocabulary, and become familiar with the fundamental principles of traditional Qur'anic exegesis.This book was compiled and published as curricula for Tajan Quran Institute (Allentown, PA, USA), but is perfectly suitable for self-study as well (in shā Allāh). All proceeds from its sales will go towards advancing the Qur'anic literacy of our students at Tajan.
