Anas said when some meat was brought to the Prophet ﷺ , he asked What is this? He was told this is a thing (meat), which was given as sadaqah to Barirah. Thereupon, he said it is sadaqah for her and a gift to us.  

أَنَّ النَّبِيَّ ﷺ أُتِيَ بِلَحْمٍ قَالَ مَا هَذَا قَالُوا شَىْءٌ تُصُدِّقَ بِهِ عَلَى بَرِيرَةَ فَقَالَ هُوَ لَهَا صَدَقَةٌ وَلَنَا هَدِيَّةٌ
