Musnad Ahmad 2220

It was narrated that Ibn 'Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) circumambulated the House and started touching the [Black] Stone with his crooked stick. Then he went to where water was offered after he finished, and his paternal cousins were drawing water from it. He said: “Give me some.” A bucket was lifted up to him and he drank, then he said: “Were it not that the people would take it as a ritual and overwhelm you, I would have drawn water alongside you.” Then he went out, and went between as-Safa and al Marwah.
