I asked Abu Abdullah (as): "What if a drop of blood appears in the sperm-drop (nutfah)?" Imam (as) replied: "For a single drop, it is one-tenth of the compensation for the nutfah, which is twenty-two dinars." I asked: "What if there are two drops?" Imam (as) said: "Then it is twenty-four dinars." I asked: "What if there are three drops?" Imam (as) said: "Then it is twenty-six dinars." I asked: "And four drops?" Imam (as) said: "Then twenty-eight dinars. And for five drops, it is thirty dinars." Imam (as) continued: "If it exceeds half of the sperm, then the compensation is calculated accordingly until it becomes a clot ('alaqah). When it reaches the stage of a clot, the compensation is forty dinars."
