English translation
2265. 'Amr bin Shu'āib narrated from his father, from his grandfather, that the Prophet ﷺ ruled regarding those who wished to be considered as inheritors after their father's death — meaning those whom they ascribed themselves to. He ruled that any child that was born to a slave owned by her master, when he engaged in intercourse with her, would be considered as a part of the one who considered him (as a son). But he will not be given any inheritance that had already been distributed before him. He will, however, be given his portion of the inheritance that has not yet been distributed. And such (a child) will not be considered a son if his father denied him. And if the child was from a slave whom he did not own, or from a free woman whom he had fornicated with, then the child will not be considered as his, nor will he inherit from him, even if the one who is considered his father accepts that he is the father, and that is because he is the child of fornication, regardless of whether it was from a free woman or a slave-girl. (Hasan)
