Hadith 51:11
Narrated Abu Huraira:
Whenever a meal was brought to Allah's Messenger (ﷺ), 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 "
