As for what the water-drawing camels (al-sawani) and waterwheels (al-dawali) water, then there is half of the tenth (5%).” So I (narrator) said to Imam عليه السلام: “The land we have is watered by waterwheels, then the water increases and it is watered by flowing water (sayh).” Imam عليه السلام said: “Indeed, that happens among you like that?” I replied: “Yes.” Imam عليه السلام said: “Half and half: half with half of the tenth, and half with the tenth.” So I (narrator) asked: “And the land is watered by waterwheels, then the water increases, and it is watered once or twice by flowing water.” Imam عليه السلام said: “And how much is it watered once or twice by flowing water?” I (narrator) replied: “In thirty nights, forty nights, while before that it had remained in the land for six months, seven months.” Imam عليه السلام said: “Half of the tenth.”
