وَعَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: مَنْ نَامَ عَنْ حِزْبِهِ من الليل، أَوْ عَنْ شيء مِنْهُ فَقَرَأَهُ مَا بَيْنَ صَلاَةِ الْفَجْرِ وَصَلاَةِ الظُّهْرِ، كُتِبَ لَهُ كَأَنَّمَا قَرَأَهُ مِنَ اللَّيْلِ ((رَوَاهُ مُسْلِم)).
'Umar bin Al-Khattab (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "Should anyone fall asleep at night and fail to recite his portion of the Qur'an, or a part of it, if he recites it between the Fajr prayer and the Zuhr prayer, it will be recorded for him as though he had recited it during the night". [Muslim].
