Anas reported that Allah's Apostle (ﷺ) said:
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 " .
I entered Paradise and heard the noise of steps. I said: Who is it? They said: She is Ghumaisa, daughter of Milhan, the mother of Anas b. Malik.
