I was present with Yunus Al-Shaybani while Abu Abdullah (as) was informing him about blood money (diyat). I asked Imam (as): "What if the sperm-drop (nutfah) came out mixed with blood?" Imam (as) replied: "If it has clotted and the blood is pure, then it is forty dinars. But if it is black blood, then there is nothing upon him except disciplinary punishment (taʿzir), because pure blood is for the child, while black blood is from within the body." Abu Shibl asked: "What if the clot (Alaqah) has a vein-like piece of flesh in it?" Imam (as) replied: "It is forty-two dinars, with one-tenth of it." I asked: "Is one-tenth of forty not four?" Imam (as) said: "It is one-tenth of the muḍghah (chewed-like substance) because only one-tenth of it was lost. As it grows, the amount increases until it reaches sixty." I asked: "I saw in the muḍghah something like a solid bone knot." Imam (as) said: "That is the bone, which initially starts with four dinars. If it increases, then add four more until it completes eighty dinars. Similarly, when the bone is covered with flesh, it follows the same ruling." I asked: "If a woman was struck, causing the fetus to miscarry and it is not known whether the fetus was alive or not?" Imam (as) replied: "Far from it, O' Abu Shibl! Once five months have passed, life has been instilled in it, and full blood money (diyyah) becomes obligatory."
