Sahih Muslim, 2279 d
sahih

Anas reported Allah's Messenger (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.

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ بِالزَّوْرَاءِ فَأُتِيَ بِإِنَاءِ مَاءٍ لاَ يَغْمُرُ أَصَابِعَهُ أَوْ قَدْرَ مَا يُوَارِي أَصَابِعَهُ ‏.‏ ثُمَّ ذَكَرَ نَحْوَ حَدِيثِ هِشَامٍ ‏.‏
