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. (Using translation from Ibn Mājah 3416)
كَانَ أَنَسٌ يَتَنَفَّسُ فِي الْإِنَاءِ مَرَّتَيْنِ أَوْ ثَلَاثًا وَزَعَمَ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ «يَتَنَفَّسُ فِي الْإِنَاءِ مَرَّتَيْنِ أَوْ ثَلَاثًا»
