The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated from Abu Al-Qasim Ja‘far bin Muhammad, from Muhammad bin Ya‘qub, from a group of our companions, from Sahl bin Ziyad, from Ali bin Mahziyar, from Muhammad bin Al-Fudhayl. He said: "I wrote to Abu Ja‘far عليه السلام, asking him about what should be done with a miscarried fetus (siqt).” Imam عليه السلام wrote back to me: 'The miscarried fetus should be buried with its blood in its place.'"
