Sahih al-Bukhari, Hadith 2576 ⓘ

Narrated Abu Huraira: Whenever a meal was brought to Allah's Messenger, he would ask whether it was a gift or Sadaqa (something given in charity). If he was told that it was Sadaqa, he would tell his companions to eat it, but if it was a gift, he would hurry to share it with them.

حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنَا مَعْنٌ، قَالَ حَدَّثَنِي إِبْرَاهِيمُ بْنُ طَهْمَانَ، عَنْ مُحَمَّدِ بْنِ زِيَادٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏إِذَا أُتِيَ بِطَعَامٍ سَأَلَ عَنْهُ أَهَدِيَّةٌ أَمْ صَدَقَةٌ فَإِنْ قِيلَ صَدَقَةٌ‏.‏ قَالَ لأَصْحَابِهِ كُلُوا‏.‏ وَلَمْ يَأْكُلْ، وَإِنْ قِيلَ هَدِيَّةٌ‏.‏ ضَرَبَ بِيَدِهِ صلى الله عليه وسلم فَأَكَلَ مَعَهُمْ ‏" ‏‏.‏
