5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn ’Isma‘il from ‘Uthman ibn ‘Isa from Zur’ah from Sama‘ah who has said the following: “I once asked abu al-Hassan, al-Awwal عليه السلام, about a miscarried child whose body is complete if Ghusl (bath) is necessary as well as al-Lahad (a horizontal or vertical) ditch in the grave). He (the Imam) said, ‘All of such things are necessary.’”
