Musnad Ahmad 30:3768

I read to Abd al-Rahman: Malik, from Khubayb ibn Abd al-Rahman, 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 cistern."
