(11) باب فِي مَنْ نَامَ عَنِ الصَّلاَةِ، أَوْ نَسِيَهَا
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".
