It was narrated from Anas that he used to drink from a vessel in three draughts, and Anas said that the Messenger of Allah ﷺ used to drink from a vessel in three draughts.  

أَنَّهُ كَانَ يَتَنَفَّسُ فِي الإِنَاءِ ثَلاَثًا وَزَعَمَ أَنَسٌ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَتَنَفَّسُ فِي الإِنَاءِ ثَلاَثًا  

It was narrated from Ibn ‘Abbas that the Prophet ﷺ drank, and took two breaths while doing so.  

أَنَّ النَّبِيَّ ﷺ شَرِبَ فَتَنَفَّسَ فِيهِ مَرَّتَيْنِ
