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 At-Tawba 9:93 through Hud 11:5. It finishes At-Tawba on those who stayed behind from campaign and those whose repentance was accepted, then gives Yunus ('Jonah') on divine signs and the mercy shown to Jonah's city, before the opening verses of Hud.
Yunus, named for the prophet Jonah, is unusual among the Quran's prophetic narratives for recounting a community, Jonah's city, that repented and was spared destruction after a prophet had already despaired of it and departed (10:98), a deliberate contrast with the recurring pattern of rejection and ruin found elsewhere in the same juz's material on Ad and Thamud in the closing verses of At-Tawba. Hud, which the juz then opens, gathers several of these same prophetic narratives, Noah, Hud, Salih, into a single sustained sequence, giving the surah its traditional character as a summary lesson in patient endurance under prolonged rejection.
