عَن حَفْصَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ لَمْ يَجْمَعِ الصِّيَامَ قَبْلَ الْفَجْرِ فَلَا صِيَامَ لَهُ» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ وَالدَّارِمَيُّ وَقَالَ أَبُو دَاوُد: وَقفه على حَفْصَة معمر والزبيدي وَابْنُ عُيَيْنَةَ وَيُونُسُ الَأَيْلِيُّ كُلُّهُمْ عَنِ الزُّهْرِيِّ

Anas said that the Prophet used to break his fast before praying with some fresh dates, but if there were no fresh dates he had a few dry dates, and if there were no dry dates he took some mouthfuls* of water.*Mirqat explains this as three mouthfuls, but 'three' does not occur in the text.Tirmidhi and Abu Dawud transmitted it, Tirmidhi saying that this is a hasan gharib tradition.
