Hizb 42

Hizb 42 closes Luqman with a warning against following ancestral custom blindly and one of the Quran's most quoted closing statements, that knowledge of the Hour, of when rain will fall, of what is in the wombs, of what any soul will earn tomorrow, and of where any soul will die belongs to God alone among five things no created being can claim to know.

The hizb then opens Al-Ahzab, the Confederates, named for the coalition of tribes that besieged Medina in an episode known as the Battle of the Trench. It reforms the pre-Islamic practice of adoption, ending the custom of treating an adopted son as a blood son for purposes of inheritance and lineage, a change tied historically to the case of Zayd ibn Harithah, the Prophet's own adopted son. Instructions follow for the Prophet's wives, addressed collectively as Mothers of the Believers, on conduct and modesty befitting their position.

The hizb closes describing the community's fear during the siege itself, hearts reaching to the throats as the sura puts it, and the hypocrites' wavering loyalty exposed under that same pressure, a vivid account of a specific historical crisis rather than a general moral teaching.

The Zaynab marriage and the seal of the prophets verse are often taught together for exactly this reason, since the first resolves a specific social taboo the earlier reform had created and the second states a doctrine of much broader and lasting theological consequence, both landing within the same short stretch of text.

Hizb 42 closes Juz 21, crossing from Luqman's closing wisdom into Al-Ahzab's opening legal reform and historical narrative, a shift from timeless paternal advice into a specific, dated communal crisis that is as sharp as any crossing this account has traced across the middle third of the Quran.

In tarawih recitation this hizb typically closes the twenty second night, and because the adoption reform carried here has had lasting consequence for Islamic family law regarding lineage and inheritance, teachers of jurisprudence frequently return to this hizb specifically when tracing how a single Quranic reform reshaped an entire pre-existing social custom rather than merely regulating it.

Huffaz reviewing this hizb by quarter typically find the five keys passage that closes Luqman the easiest single unit to isolate and recall, a short, self-contained, rhythmically balanced list, before the far longer and more historically specific material of Al-Ahzab's opening quarters requires a different, more contextual kind of memory work entirely.

Because the trust passage addresses humanity in the abstract while the surrounding material addresses one specific household and one specific siege, reciters sometimes describe this hizb as moving between the most concrete and the most universal material found anywhere within a single set of four rub al-hizb quarters.
