Sunan an-Nasa'i 2613
أَخْبَرَنَا زِيَادُ بْنُ أَيُّوبَ، قَالَ حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ وَاصِلٍ، قَالَ حَدَّثَنَا بَهْزُ بْنُ حَكِيمٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أُتِيَ بِشَىْءٍ سَأَلَ عَنْهُ " أَهَدِيَّةٌ أَمْ صَدَقَةٌ " . فَإِنْ قِيلَ صَدَقَةٌ لَمْ يَأْكُلْ وَإِنْ قِيلَ هَدِيَّةٌ بَسَطَ يَدَهُ .
Ziyad ibn Ayyub reported: Abd al-Wahid ibn Wasid narrated to us: Bahz ibn Hakim narrated to us, from his father, from his grandfather, who said: Whenever the Prophet ﷺ was brought something, he would ask: Is it a gift or charity? If he was told it was charity, he would not eat it. If he was told it was a gift, he would extend his hand.
Translation notes
The report distinguishes gifts from charity by whether the Prophet ate it or extended his hand.
