حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا عَبْدُ الرَّحِيمِ بْنُ سُلَيْمَانَ، عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي سُلَيْمَانَ، عَنْ عَطَاءٍ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنْ فَطَّرَ صَائِمًا كَانَ لَهُ مِثْلُ أَجْرِهِ غَيْرَ أَنَّهُ لاَ يَنْقُصُ مِنْ أَجْرِ الصَّائِمِ شَيْئًا ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏

Zaid bin Khalid Al-Juhani narrated that: The Messenger of Allah said: "Whoever provides the food for a fasting person to break his fast with, then for him is the same reward as his (the fasting person's), without anything being diminished from the reward of the fasting person."
