Sayyiduna Abu Musa (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) "cursed the one who separates a father and his child, and two brothers."
The Shaykh says: This Ibrahim bin Isma'il bin Mujammi' is not used as proof. It has also been reported from him (through another chain) that Sayyiduna Abu Musa (may Allah be pleased with him) narrates it from the Prophet (peace and blessings be upon him) concerning a father and his child.
