عَنْ أَنَسٍ
قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَنَفَّسُ فِي الشَّرَابِ ثَلَاثًا
God’s messenger used to breathe three times in the course of a drink. (Bukhari and Muslim.) In a version Muslim added that he used to say, “It is more thirst-quenching, healthier and more wholesome.”
