The Surah Without a Bismillah Begins

Juz 10 finishes Al-Anfal's final thirty-five verses before opening At-Tawba, the one surah in the Quran without an opening Bismillah, and carries its first ninety-two of one hundred and twenty-nine verses, meaning most of this juz belongs to the surah later tradition remembers for the absence of that formula rather than to the one it closes.

In communities that pace the nightly tarawih prayers of Ramadan at one juz per night, this is customarily the tenth night's portion, though many mosques recite faster to finish early in the month or slower to spread the reading further, and some congregations instead divide the whole Quran among thirty reciters for a single collective khatm. Huffaz reviewing memorised portions often pace themselves by a juz's two hizb and four quarter-hizb divisions rather than by surah, since these evenly sized units make a consistent daily review schedule possible regardless of where a surah boundary falls. Printed Mushafs typically mark each juz's opening in the margin with a small medallion inscribed with its number, a page-level convention distinct from the finer hizb and quarter-hizb marks placed within the text itself to guide reciters mid-portion. Some Mushaf editions additionally shade or border the margin differently for each hizb, so a reciter can judge progress through the juz at a glance without counting verses.
