وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا بِشْرٌ، - يَعْنِي ابْنَ السَّرِيِّ - حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " دَخَلْتُ الْجَنَّةَ فَسَمِعْتُ خَشْفَةً فَقُلْتُ مَنْ هَذَا قَالُوا هَذِهِ الْغُمَيْصَاءُ بِنْتُ مِلْحَانَ أُمُّ أَنَسِ بْنِ مَالِكٍ " .
