Musannaf Ibn Abi Shayba 18:631

Abu Bakr narrated to us, he said: Jarir narrated to us, from Ata’ ibn al-Sa’ib, from Shurayh, who said: He used to hold liable [the owners of] the cesspools which they would construct in the road, and the mule stalls, and the wood which is placed in the walls. And he would not hold liable the outer wells which were in front of Kufa in the open desert, and those which were in the graveyards, and that which was made for the benefit of the Muslims.
