A juz (plural ajza), also called a para in South Asia, is one of thirty roughly equal divisions of the written Quran. The division is made by length rather than by meaning, so a juz usually begins and ends in the middle of a surah; each is further split into two hizb and each hizb into quarters. Reciting one juz a night completes the whole Quran across a lunar month, a rhythm tied above all to Ramadan, when the entire text is recited in the nightly tarawih prayers. This portion spans Al-Mulk 67:1 through Al-Mursalat 77:50. Named Tabaraka after its opening word, this juz begins with Al-Mulk ('The Sovereignty'), traditionally recited each night as a protection, and gathers short Meccan surahs, Al-Qalam ('The Pen'), Al-Haqqa, Nuh ('Noah'), Al-Jinn, Al-Muzzammil and Al-Muddaththir among the earliest revelations, through Al-Mursalat.
Al-Mujadila, opening this run of Medinan surahs on community life, preserves one of the very few Quranic passages naming and responding directly to a specific woman's individual legal complaint, traditionally identified as Khawla bint Tha'laba, whose husband had pronounced a form of divorce-like oath against her (zihar); the surah's opening verses reform the practice's legal consequences in direct response. Al-Jumua's legislation of the Friday congregational prayer (62:9-10), read later in the juz, remains one of the most universally observed pieces of Quranic ritual law across the entire Muslim world regardless of school or region.
