The Book of Qiyam Al-Lail (The Night Prayer) and Voluntary Prayers During the Day
20/65. Chapter:
When should a person who slept and missed reciting his nightly portion of Qur'an make it up
Sunan an-Nasai
أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ، عَنْ شُعْبَةَ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عُمَرَ، قَالَ مَنْ فَاتَهُ وِرْدُهُ مِنَ اللَّيْلِ فَلْيَقْرَأْهُ فِي صَلاَةٍ قَبْلَ الظُّهْرِ فَإِنَّهَا تَعْدِلُ صَلاَةَ اللَّيْلِ .
It was narrated that Humaid bin Abdur-Rahman said: "Whoever misses his Wird at night, let him recite it during prayer before Zuhr, and that will be equivalent to night prayers."
