It is narrated from Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever digs a well, it is not permissible for anyone else to dig a well within forty cubits around it for watering and resting their animals (i.e., the area of forty cubits around the well should be left for the one who dug it)."
