The first juz of the Quran, known as "Alif Lam Meem," covers Surah Al-Fatiha and the beginning of Surah Al-Baqarah (verses 1-141). Surah Al-Fatiha, the opening chapter, is a short, powerful prayer that praises Allah and asks for guidance on the straight path. Surah Al-Baqarah, the longest chapter, begins with a call to believe in the unseen, establish prayer, and spend in charity. It addresses the story of Adam and the fall from paradise, emphasizing human responsibility and repentance. The surah discusses the Children of Israel, highlighting their covenant with Allah and their subsequent disobedience, serving as a lesson for the believers. It underscores the importance of faith, patience, and adherence to divine guidance, setting the stage for the Quran's comprehensive message of monotheism, morality, and law.
