Sahih Muslim 164b
It is reported on the authority of Malik b. Sa'sa' that the Messenger of Allah ﷺ narrated the hadith (mentioned above) and added to it: I was brought a gold basin full of wisdom and faith, and then the (part of the body) right from the upper end of the chest to the lower part of the abdomen was opened and it was washed with the water of Zamzam and then flled with wisdom and faith.
حَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، عَنْ مَالِكِ بْنِ صَعْصَعَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فَذَكَرَ نَحْوَهُ وَزَادَ فِيهِ " فَأُتِيتُ بِطَسْتٍ مِنْ ذَهَبٍ مُمْتَلِئٍ حِكْمَةً وَإِيمَانًا فَشُقَّ مِنَ النَّحْرِ إِلَى مَرَاقِّ الْبَطْنِ فَغُسِلَ بِمَاءِ زَمْزَمَ ثُمَّ مُلِئَ حِكْمَةً وَإِيمَانًا " .
