Musannaf Ibn Abi Shayba 33:1294

'Affan narrated to us, he said: Sulayman ibn al-Mughirah narrated to us, he said: Humayd ibn Hilal narrated to us, he said: Abu Rifa'ah, or a man among them, used to heat water for his companions while traveling. He would then intend to use the cold water and perform ablution with it, then say: "Do well with this, and I will do well with this."
