Sunan Abu Dawud, hadith 1655

حَدَّثَنَا عَمْرُو بْنُ مَرْزُوقٍ، قَالَ أَخْبَرَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أُتِيَ بِلَحْمٍ قَالَ ‏"‏ مَا هَذَا ‏"‏ ‏.‏ قَالُوا شَىْءٌ تُصُدِّقَ بِهِ عَلَى بَرِيرَةَ فَقَالَ ‏"‏ هُوَ لَهَا صَدَقَةٌ وَلَنَا هَدِيَّةٌ ‏"‏ ‏.‏
