Narrated Ibn 'Umar (RA):

Bilal called for prayer before dawn and the Prophet (ﷺ) told him to return and announce: "Lo! the slave of Allah (i.e. Bilal) had slept (hence this mistake)". [Reported by Abu Dawud, and graded as Da'if (weak)].

وَعَنْ اِبْنِ عُمَرَ; { إِنَّ بِلَالاً أَذَّنَ قَبْلَ اَلْفَجْرِ, فَأَمَرَهُ اَلنَّبِيُّ ‏- صلى الله عليه وسلم ‏-أَنْ يَرْجِعَ, فَيُنَادِيَ: "أَلَا إِنَّ اَلْعَبْدَ نَامَ } رَوَاهُ أَبُو دَاوُدَ وَضَعَّفَهُ [1]‏ .‏
