MUSLIM 747:
from ʿUmar b. al-Khaṭṭāb —
Should anyone fall asleep and fail to recite his portion of the Qur'an, or a part of it, if he recites it between the dawn prayer and the noon prayer, it will be recorded for him as though he had recited it during the night.
مسلم ٧٤٧:
عن عمر بن الخطاب —
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ نَامَ عَنْ حِزْبِهِ أَوْ عَنْ شَىْءٍ مِنْهُ فَقَرَأَهُ فِيمَا بَيْنَ صَلاَةِ الْفَجْرِ وَصَلاَةِ الظُّهْرِ كُتِبَ لَهُ كَأَنَّمَا قَرَأَهُ مِنَ اللَّيْلِ
