Four Surahs, End to End, Ending Clean

Juz 25 packs an unusual number of complete surahs into a single division: after finishing Fussilat's last eight verses, it carries four complete surahs back to back, Ash-Shura, Az-Zukhruf, Ad-Dukhan and Al-Jathiya, fifty-three, eighty-nine, fifty-nine and thirty-seven verses respectively, ending precisely on Al-Jathiya's final verse, another instance of a juz boundary landing exactly on a surah's own close.

In communities that pace the nightly tarawih prayers of Ramadan at one juz per night, this is customarily the twenty-fifth 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, and printed Mushafs typically mark each juz's opening in the margin with a small medallion inscribed with its number. Many print editions, including the widely used 604-page Uthmani Mushaf standardised by Saudi Arabia's King Fahd Complex, begin each juz on a fresh page and hold each to roughly twenty pages, letting a reciter track a night's target by page count alone without consulting verse numbers.
