«كان يستعذب له الماء من بيوت السقيا; وفي لفظ: يستسقى له الماء العذب من بئر السقيا»
It was the practice of the Prophet (peace and blessings be upon him):
"Sweet water would be brought for him (peace and blessings be upon him) from the houses of as-Suqya; in one narration: sweet water would be fetched for him from the well of as-Suqya."
