Umar ibn al-Khattab (r.a.) said, “He who slept without doing his hizb, or any part of it, then read it sometime between  the Fajr and Zuhr prayers, it will be written for him as if he had read it at night.”

Narrated by Abdullah ibn Mubarak. A hizb is one half of a Juz’, which means about 1/60th of the Qur’an, but here it probably stands for whatever your daily wird is.
