It is narrated from Sayyiduna Ri'yah al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) wrote him a letter and sent it to him, and he used it to patch his bucket. Then a detachment of the Messenger of Allah (peace and blessings be upon him) passed by him and drove off his camels; then he (Ri'yah) became a Muslim. The Messenger of Allah (peace and blessings be upon him) said to him: "Whatever of your property you find exactly as it was (unchanged) before it is distributed, you have the most right to it."
