حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ، حَدَّثَنَا ثَابِتٌ الْبُنَانِيُّ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُفْطِرُ عَلَى رُطَبَاتٍ قَبْلَ أَنْ يُصَلِّيَ فَإِنْ لَمْ تَكُنْ رُطَبَاتٌ فَعَلَى تَمَرَاتٍ فَإِنْ لَمْ تَكُنْ حَسَا حَسَوَاتٍ مِنْ مَاءٍ ‏.‏

Narrated Anas ibn Malik: The Messenger of Allah (PBUH) 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. Translation Not Available
