Musnad Ahmad — Hadith 24009/26

Abdu al-Samad narrated to us, Mulazim narrated to us, Abdullah ibn Badr narrated to us, and Siraj ibn Uqbah, that his uncle Qays ibn Taliq narrated to him, that his father Taliq ibn Ali narrated to him, that a delegation went to the Messenger of Allah, peace and blessings be upon him, until they reached him, and they informed him that in their land there was a church, and they asked him for some of his leftover purification water. So he called for water, performed ablution, rinsed his mouth in a vessel, and said: "Take this water, and when you arrive at your land, break your church and sprinkle its place with this water, and make it a mosque." He said: We said: O Prophet of Allah, we go out in a time of much hot wind and heat, and the water dries up. He said: "Then add water to it, for there will remain in it much strength and moisture." He said: So we went out until we reached our land, broke our church, sprinkled its place with that water, and made it a mosque.
