الشرب في ثلاثة أنفاس
A reported practice of drinking in three separate breaths/sips rather than a single continuous gulp, removing the cup from the mouth between each.
كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَنَفَّسُ فِي الشَّرَابِ ثَلَاثًا
“The Messenger of Allah ﷺ would take three breaths [pauses] while drinking.” (meaning, not a literal translation)
He is reported to have said this was more thirst-quenching, more wholesome, and easier on the body (Sahih Muslim 2028).
Ibn al-Qayyim connects this to broader digestive advice against consuming anything, food or drink, too quickly for the stomach to process comfortably.
