Abu Hurairah reported:
When the Messenger of Allah ﷺ returned from the Battle of Khaibar, he travelled during the night. When we felt sleep, he halted for rest. Addressing Bilal he said: Keep vigilance at night for us. But Bilal who was leaning against the saddle of his mount was dominated by sleep. Neither the Prophet ﷺ nor Bilal nor any of his Companions could get up till the sunshine struck them. The Messenger of Allah ﷺ got up first of all. The Messenger of Allah ﷺ was embarrassed and said: O Bilal ! He replied: He who detained your soul, detained my soul, Messenger of Allah, my parents be sacrificed for you. Then they drove their mounts to a little distance. The Prophet ﷺ perfumed ablution and commanded Bilal who made announcement for the prayer. He (the Prophet) led them in the Fajr prayer. When he finished prayer, he said: If anyone forget saying prayer, he should observe it when he recalls it, for Allah has said (in the Qur'an): "Establish prayer for my remembrance". Yunus said: Ibn Shihab used to recite this verse in a similar way (i.e. instead of reciting the word li-dhikri - for the sake of My remembrance - he would recite li-dhikra - when you remember). Ahmad (one of the narrator) said: 'Anbasah (a reporter) reported on the authority of Yunus the word li-dhikri (for the sake of my remembrance). Ahmad said: The word nu'as (occurring in this tradition) means "drowsiness".

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ حِينَ قَفَلَ مِنْ غَزْوَةِ خَيْبَرَ فَسَارَ لَيْلَةً حَتَّى إِذَا أَدْرَكَنَا الْكَرَى عَرَّسَ وَقَالَ لِبِلاَلٍ " اكْلأْ لَنَا اللَّيْلَ " . قَالَ فَغَلَبَتْ بِلاَلاً عَيْنَاهُ وَهُوَ مُسْتَنِدٌ إِلَى رَاحِلَتِهِ فَلَمْ يَسْتَيْقِظِ النَّبِيُّ ﷺ وَلاَ بِلاَلٌ وَلاَ أَحَدٌ مِنْ أَصْحَابِهِ حَتَّى إِذَا ضَرَبَتْهُمُ الشَّمْسُ فَكَانَ رَسُولُ اللَّهِ ﷺ أَوَّلَهُمُ اسْتِيقَاظًا فَفَزِعَ رَسُولُ اللَّهِ ﷺ فَقَالَ " يَا بِلاَلُ " . فَقَالَ أَخَذَ بِنَفْسِي الَّذِي أَخَذَ بِنَفْسِكَ بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللَّهِ فَاقْتَادُوا رَوَاحِلَهُمْ شَيْئًا ثُمَّ تَوَضَّأَ النَّبِيُّ ﷺ وَأَمَرَ بِلاَلاً فَأَقَامَ لَهُمُ الصَّلاَةَ وَصَلَّى بِهِمُ الصُّبْحَ فَلَمَّا قَضَى الصَّلاَةَ قَالَ " مَنْ نَسِيَ صَلاَةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا فَإِنَّ اللَّهَ تَعَالَى قَالَ { أَقِمِ الصَّلاَةَ لِلذِّكْرَى } " . قَالَ يُونُسُ وَكَانَ ابْنُ شِهَابٍ يَقْرَؤُهَا كَذَلِكَ . قَالَ أَحْمَدُ قَالَ عَنْبَسَةُ - يَعْنِي عَنْ يُونُسَ - فِي هَذَا الْحَدِيثِ لِذِكْرِي . وَقَالَ أَحْمَدُ الْكَرَى النُّعَاسُ .
