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 An-Nisa 4:24 through 4:147. A legislative stretch of An-Nisa on marriage, the just treatment of women and dependents, arbitration in disputes, the shortened prayer in times of danger, and repeated warnings against the hypocrites of Medina.
An-Nisa's legislative material in this portion, on marriage, the treatment of orphans and the shortened prayer during travel or danger (4:101), is traditionally read against the backdrop of Medina's fragile early years, when military expeditions and an uneasy relationship with the so-called hypocrites, Medinan residents who outwardly professed Islam while working against the community, made both physical safety and social cohesion urgent concerns; classical exegetes accordingly treat much of this juz as occasion-specific legislation whose underlying principles are then generalised in later jurisprudence.
