Mishkat al-Masabih 4 Prayer كتاب الصلاة 662

وَعَن عمر رَضِي الله ع نه قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ نَامَ عَنْ حِزْبِهِ أَوْ عَنْ شَيْءٍ مِنْهُ فَقَرَأَهُ فِيمَا بَيْنَ صَلَاةِ الْفَجْرِ وَصَلَاةِ الظُّهْرِ كُتِبَ لَهُ كَأَنَّمَا قَرَأَهُ مِنَ اللَّيْل» . رَوَاهُ مُسلم

‘Umar reported God’s Messenger as saying, “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 and the noon prayer it will be recorded for him as though he had recited it during the night.” Muslim transmitted it.
