Kathir bin Abdullah narrates from his father, and he from his grandfather (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) said: "Whoever revives barren land without (taking) the right of a Muslim, it is his, and the one with an unjust root has no right."
