The Prophet ﷺ said: A woman gets inheritance from the three following: one she has set free, a foundling, and her child about whom she has invoked a curse on herself if she was untrue in declaring he was not born out of wedlock.  

عَنِ النَّبِيِّ ﷺ قَالَ الْمَرْأَةُ تُحْرِزُ ثَلاَثَةَ مَوَارِيثَ عَتِيقَهَا وَلَقِيطَهَا وَوَلَدَهَا الَّذِي لاَعَنَتْ عَنْهُ  

The Messenger of Allah ﷺ assigned the estate of a child of a woman about whom she had invoked a curse to her mother, and to her heirs after her.  

جَعَلَ رَسُولُ اللَّهِ ﷺ مِيرَاثَ ابْنِ الْمُلاَعِنَةِ لأُمِّهِ وَلِوَرَثَتِهَا مِنْ بَعْدِهَا  

On his father's authority, said that his grandfather reported from the Prophet ﷺ something similar.  

عَنِ النَّبِيِّ ﷺ مِثْلَهُ
