Musnad Ahmad 30:1764

Muhammad ibn Ubayd narrated to us, Ubaydullah narrated to us, from Khubayb—meaning Ibn Abd al-Rahman ibn Yasaf—from Hafs ibn Asim, from Abu Hurayrah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "What is between my house and my pulpit is a garden from the gardens of Paradise, and my pulpit is upon my basin."
