'Umar bin Al-Khattab (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said: "If anyone falls asleep and therefore fails to observe his Hizb (share) or part of it, if he observes it between the Fajr and the Zuhr prayers, it will be recorded for him as though he had observed it during the night."

[Muslim].

وعن عمر بن الخطاب، رضي الله عنه، قال: قال رسول الله ﷺ : "من نام عن حزبه، أو عن شيء منه، فقرأه فيما بين صلاة الفجر وصلاة الظهر، كتب له كأنما قرأه من الليل" ((رواه مسلم)).
