Musnad Ahmad 33:942

Yazid narrated to us, 'Abd al-Malik narrated to us, from Abu al-Zubayr, from Jabir ibn 'Abd Allah, who said: "The Messenger of Allah (peace and blessings of Allah be upon him) would have nabidh (a drink made by soaking dates or raisins in water) prepared for him in a waterskin. If there was no waterskin, it would be prepared for him in a stone basin."
