Musnad Ahmad 30:2878

I read to Abd al-Rahman: Malik, from Khubayb, and Ishaq narrated to us, Malik informed us, from Khubayb, from Hafs ibn Asim, from Abu Hurayrah, or from Abu Sa'id al-Khudri, that the Messenger of Allah, may Allah bless him and grant him peace, said: "What is between my house and my pulpit is a garden from the gardens of Paradise, and my pulpit is upon my basin."
