Al-Zubayr bin Adi said: In the time of Sayyiduna Ali (may Allah be pleased with him), a dihqan (local landlord) from the people of the Sawad accepted Islam. Sayyiduna Ali (may Allah be pleased with him) said to him: If you remain on your land, we will remove your jizyah and collect the tax on your land; and if you move away from it, we have more right to that land.
