كتاب الصيام
The Book of Fasting
باب بَيَانِ أَنَّ الدُّخُولَ فِي الصَّوْمِ يَحْصُلُ بِطُلُوعِ الْفَجْرِ وَأَنَّ لَهُ الأَكْلَ وَغَيْرَهُ حَتَّى يَطْلُعَ الْفَجْرُ وَبَيَانِ صِفَةِ الْفَجْرِ الَّذِي تَتَعَلَّقُ بِهِ الأَحْكَامُ مِنَ الدُّخُولِ فِي الصَّوْمِ وَدُخُولِ وَقْتِ صَلاَةِ الصُّبْحِ وَغَيْرِ ذَلِكَ:
Chapter: Clarifying that fasting begins at dawn, and a person may eat and other than that until dawn begins; And clarifying the dawn which has to do with the rulings concerning the beginning of fasting and the beginning of the time for the Subh Prayer, and other than that, which is the Second Dawn, which is called the True Dawn. The First Dawn, which is the False Dawn, has nothing to do with the rulings
Hadith 1094
This hadith is listed as number 2544 in Maktaba Shamila
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ ، حَدَّثَنَا عَبْدُ الْوَارِثِ ، عَنْ عَبْدِ اللَّهِ بْنِ سَوَادَةَ الْقُشَيْرِيِّ ، حَدَّثَنِي وَالِدِي ، أَنَّهُ سَمِعَ سَمُرَةَ بْنَ جُنْدُبٍ ، يَقُولُ : سَمِعْتُ مُحَمَّدًا صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، يَقُولُ : " لَا يَغُرَّنَّ أَحَدَكُمْ نِدَاءُ بِلَالٍ مِنَ السَّحُورِ ، وَلَا هَذَا الْبَيَاضُ حَتَّى يَسْتَطِيرَ " .
ahadeeth bin Jandub reported Muhammad (ﷺ) as saying. The call of Bilal (RA) 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.
