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

Abu Huraira reported God’s messenger as saying, “When any of you hears the summons to prayer while he has a vessel in his hand he should not lay it down till he finishes his drink.”* *This is interpreted as referring to the dawn prayer during Ramadan.Abu Dawud transmitted it.
