4. Al-Husayn from Muhammad has narrated from Mu‘alla’ ibn Muhammad from certain persons of his people from Aban ibn ‘Uthman from ‘Abd al- Rahman ibn abu ‘Abd Allah who has narrated the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a child of Mula‘anah and about who inherits such a child. He (the Imam) said, ‘The mother inherits the legacy of such child.’ I then asked, ‘Who inherits such child if the mother dies?’ He (the Imam) said, ‘The maternal uncle inherits the legacy of such child.’”
