Abdur-Rahman bin Abdul-Qari said: "I heard Umar bin Al-Khattab say: 'The Messenger of Allah said: Whoever sleeps and misses his portion (of Qur'an) or part of it, and then reads it between Fajr and Zuhr prayers, it will be recorded for him as if he had read it at night.'" (Sahih
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا أَبُو صَفْوَانَ عَبْدُ اللَّهِ بْنُ سَعِيدِ بْنِ عَبْدِ الْمَلِكِ بْنِ مَرْوَانَ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، أَنَّ السَّائِبَ بْنَ يَزِيدَ، وَعُبَيْدَ اللَّهِ، أَخْبَرَاهُ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَبْدٍ الْقَارِيَّ قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ نَامَ عَنْ حِزْبِهِ أَوْ عَنْ شَىْءٍ مِنْهُ فَقَرَأَهُ فِيمَا بَيْنَ صَلاَةِ الْفَجْرِ وَصَلاَةِ الظُّهْرِ كُتِبَ لَهُ كَأَنَّمَا قَرَأَهُ مِنَ اللَّيْلِ " .
