NASAI-KUBRA 1595:
from Dhakarūā Nawmahum —
"They told the Prophet ﷺ that they had slept and missed the prayer. He said: 'There is no negligence when one sleeps, rather negligence is when one is awake. If any one of you forgets a prayer or sleeps and misses it, let him pray it when he remembers it.'" (Using translation from Nasāʾī 615)
الكبرى للنسائي ١٥٩٥:
عن ذكروا نومهم —
إِنَّهُ «لَيْسَ فِي النَّوْمِ تَفْرِيطٌ إِنَّمَا التَّفْرِيطُ فِي الْيَقَظَةِ فَإِذَا نَسِيَ أَحَدُكُمُ صَلَاةً أَوْ نَامَ عَنْهَا فَلْيُصَلِّهَا إِذَا ذَكَرَهَا»
