When should a person who slept and missed reciting his nightly portion of Qur'an make it up
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكٍ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، عَنِ الأَعْرَجِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدٍ الْقَارِيِّ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ مَنْ فَاتَهُ حِزْبُهُ مِنَ اللَّيْلِ فَقَرَأَهُ حِينَ تَزُولُ الشَّمْسُ إِلَى صَلاَةِ الظُّهْرِ فَإِنَّهُ لَمْ يَفُتْهُ أَوْ كَأَنَّهُ أَدْرَكَهُ . رَوَاهُ حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ مَوْقُوفًا .
It was narrated from Abdur-Rahman bin Abdul-Qari that Umar bin Al-Khattab said: "Whoever misses his nightly portion and recites it from the time when the sun passes its zenith until Zuhr prayer, then he did not miss it, or it is as if he caught up with it."
