A 3:
If the miscarried fetus completed four months or more, it would be Wajib (obligatory) to wash, shroud, offer Janazah (Funeral) Prayer for it and bury it in a grave. What you did with the six month miscarried fetus was a gross mistake. It should be disinterred if possible and its remains should be wrapped and moved to the public cemetery. (Part No. 7; Page No. 241) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
