In-book no 2428حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ اللَّهِ بْنِ سَوَادَةَ الْقُشَيْرِيِّ، حَدَّثَنِي وَالِدِي، أَنَّهُ سَمِعَ سَمُرَةَ بْنَ جُنْدُبٍ، يَقُولُ سَمِعْتُ مُحَمَّدًا، صلى الله عليه وسلم يَقُولُ
Samura b. Jandub reported Muhammad (ﷺ) as saying. The call of Bilal may not mislead any one of you (and he may, under the wrong impression gathered from it, refrain) from taking meal before the commencement of the fast (for the streaks) of this whiteness (which are vertical indicate the false dawn and the true dawn with which the fast commences is that when the streaks of light are) spread.
