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

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ ، عَنْ سُلَيْمَانَ التَّيْمِيِّ ، عَنْ أَبِي عُثْمَانَ ، عَنْ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَا يَمْنَعَنَّ أَحَدًا مِنْكُمْ أَذَانُ بِلَالٍ ، أَوَ قَالَ : نِدَاءُ بِلَالٍ مِنْ سُحُورِهِ ، فَإِنَّهُ يُؤَذِّنُ ، أَوَ قَالَ : يُنَادِي بِلَيْلٍ لِيَرْجِعَ قَائِمَكُمْ وَيُوقِظَ نَائِمَكُمْ ، وَقَالَ : لَيْسَ أَنْ يَقُولَ هَكَذَا وَهَكَذَا وَصَوَّبَ يَدَهُ وَرَفَعَهَا ، حَتَّى يَقُولَ هَكَذَا وَفَرَّجَ بَيْنَ إِصْبَعَيْهِ " ،
This hadith has been narrated by Sulaiman al-Taimi with the same chain of transmitters (but with a slight variation of words) that he (the Holy Prophet) said: The dawn is not like it as it is said; he then gathered his fingers and lowered them. But he said, it is like this (and he placed the index finger upon the other one and spread his hand).
