Hadith.5696 - Mansur ibn Hazim narrated from Abu Abdullah عليه السلام who said:
"Imam Ali ibn Abi Talib عليه السلام used to say: 'If the son of the cursed woman dies and he has brothers, his wealth is divided according to the shares ordained by Allah سبحانه وتعالى, the Mighty and Majestic.'"
This means brothers from the mother's side or from both the father and mother.
As for brothers from the father's side only, they do not inherit from him. The brothers from both the father and the mother inherit only through the mother, not through the father.
Therefore, they and the brothers from the mother's side are equal in inheritance.
