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

وحَدَّثَنِي أَبُو الرَّبِيعِ الزَّهْرَانِيُّ ، حَدَّثَنَا حَمَّادٌ يَعْنِي ابْنَ زَيْدٍ ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَوَادَةَ الْقُشَيْرِيُّ ، عَنْ أَبِيهِ ، عَنْ سَمُرَةَ بْنِ جُنْدُبٍ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَا يَغُرَّنَّكُمْ مِنْ سَحُورِكُمْ أَذَانُ بِلَالٍ ، وَلَا بَيَاضُ الْأُفُقِ الْمُسْتَطِيلُ هَكَذَا ، حَتَّى يَسْتَطِيرَ هَكَذَا " ، وَحَكَاهُ حَمَّادٌ بِيَدَيْهِ ، قَالَ : يَعْنِي مُعْتَرِضًا .
ahadeeth bin Jundub (RA) reported Allah's Messenger (ﷺ) as saying: The Adhan of Bilal (RA) may not mislead you with regard to your food at the commencement of the fast, nor the vertical (streaks) of whiteness in the horizon (for it is an indication of false dawn). You should stop eating (food) till (the whiteness) spreads like it. Hammad narrated it and with the gesture of his hand he explained, the horizontal position (of the streaks of light).
