Anas reported Allah's Apostle ﷺ was at az-Zaura' and a vessel containing water was brought to him in which his finger could not be completely dipped or completely covered; the rest of the hadith is the same.  

مسلم:٢٢٧٩dوَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا سَعِيدٌ عَنْ قَتَادَةَ عَنْ أَنَسٍ

أَنَّ النَّبِيَّ ﷺ كَانَ بِالزَّوْرَاءِ فَأُتِيَ بِإِنَاءِ مَاءٍ لاَ يَغْمُرُ أَصَابِعَهُ أَوْ قَدْرَ مَا يُوَارِي أَصَابِعَهُ ثُمَّ ذَكَرَ نَحْوَ حَدِيثِ هِشَامٍ
