Abu Hurairah reported: Another version of the above tradition adds: The Messenger of Allah صلی اللہ علیہ وسلم said: Go away from this place of yours where inadvertence took hold of you. He then commanded Bilal who called for prayer and announced that the prayer in congregation was ready (i. e. he uttered the iqamah) and he observed prayer. Abu Dawud said: This tradition has been narrated by Malik, Sufyan bin Uyainah, al-Awzai, and Abd al-Razzaq from Mamar and Ibn Ishaq, none of them made a mention of the call for prayer (adman) in this version of the tradition narrated by al-Zuhri, and none of them attribute (this tradition) to him except al-Awzai and Aban al-'Attar on the authority of Mamar.

Abu Hurairah reported: When the Messenger of Allah صلی اللہ علیہ وسلم 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 صلی اللہ علیہ وسلم nor Bilal nor any of his Companions could get up till the sunshine struck them. The Messenger of Allah صلی اللہ علیہ وسلم got up first of all. The Messenger of Allah صلی اللہ علیہ وسلم 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 صلی اللہ علیہ وسلم 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 Quran): "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".

Abu Qatadah reported: "The Prophet صلی اللہ علیہ وسلم was on a journey. The Prophet صلی اللہ علیہ وسلم took a turn and I also took a turn with him. He said: 'Look!' I said: 'This is a rider; these are two riders; and these are three' until we became seven. He then said: Guard for us our prayer, i. e. the Fajr prayer. But sleep dominated them and none could awaken them except the heat of the sun. They stood up and drove away a little. Then they got down (from their mounts) and performed ablution. Bilal called for prayer and they offered two rak'ahs of (Sunnah) of Fajr and then offered the Fajr prayer and mounted (their mounts). Some of them said to others: We showed negligence in prayer. The Prophet صلی اللہ علیہ وسلم said: There is no negligence in sleep. The negligence is in wakefulness. If any of you forget saying prayer, he should offer it when he remembers it and next day (he should say it) at its proper time.
