سنن أبي داود#532Sahihحَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، وَدَاوُدُ بْنُ شَبِيبٍ، - الْمَعْنَى - قَالاَ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ بِلاَلاً، أَذَّنَ قَبْلَ طُلُوعِ الْفَجْرِ فَأَمَرَهُ النَّبِيُّ صلى الله عليه وسلم أَنْ يَرْجِعَ فَيُنَادِيَ " أَلاَ إِنَّ الْعَبْدَ قَدْ نَامَ أَلاَ إِنَّ الْعَبْدَ قَدْ نَامَ " . زَادَ مُوسَى فَرَجَعَ فَنَادَى أَلاَ إِنَّ الْعَبْدَ نَامَ . قَالَ أَبُو دَاوُدَ وَهَذَا الْحَدِيثُ لَمْ يَرْوِهِ عَنْ أَيُّوبَ إِلاَّ حَمَّادُ بْنُ سَلَمَةَ .
Narrated Abdullah ibn Umar: Bilal made a call to prayer before the break of dawn; the Prophet (ﷺ), therefore, commanded him to return and make a call: Lo! the servant of Allah (i.e. I) had slept (hence this mistake). The version of Musa has the addition: He returned and made a call: Lo! the servant of Allah had slept. Abu Dawud said: This tradition has been narrated by al-Darawardi from 'Ubaid Allah on the authority of Ibn 'Umar saying: There was a mu'adhdhin of 'Umar, named Mas'ud. He then narrated the rest of the tradition. This version is more correct than that one
