وَعَنْ أَبِي قَتَادَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " لَيْسَ فِي النَّوْمِ تَفْرِيطٌ إِنَّمَا التَّفْرِيطُ فِي الْيَقَظَةِ. فَإِذَا نَسِيَ أَحَدُكُمْ صَلَاةً أَوْ نَامَ عَنْهَا فَلْيُصَلِّهَا إِذَا ذَكَرَهَا فَإِنَّ اللَّهَ تَعَالَى قَالَ: (وَأَقِمِ الصَّلَاةَ لذكري) رَوَاهُ مُسلم
Abu Qatada reported God’s Messenger as saying, “There is no remissness in sleep, it is only when one is awake that there is remissness; so when any of you forgets a stated prayer or oversleeps, he should observe it when he remembers it, for God has said, ‘And observe the prayer for remembrance of Me’” (Al-Qur’an, 20:14). Muslim transmitted it.
