The Prophet ﷺ, when he drank, would breathe three times and say, "It is more pleasant, more wholesome, and more healing."
حدثنا مسلم بن إبراهيم حدثنا هشام عن أبي عصام
أن النبي ﷺ كان إذا شرب تنفس ثلاثا وقال هو أهنأ وأمرأ وأبرأ
Muslim narrated it, in the Book of Drinks, chapter on the dislike of breathing into the vessel itself, hadith no. 2028, from the hadith of Hisham with the same wording. Bukhari also narrated it, hadith no. 5631, from the hadith of Anas.
