[The ruling on one who killed his father because his uncles made hatred of his father seem fair to him]

Question: A boy at the stage of approaching puberty had uncles who were beautifying for him enmity towards his father and making him hate him, until he became filled with enmity and hatred toward his father. His father was sick, bedridden, and the only heirs he had were this son and the boy’s mother. This adolescent son entered upon his father when no one else was with him, and struck him a single blow on the head with a stick, and the father died from that blow. It was not a strong blow; had it been struck on a healthy man, he would not have died from it. The son concealed this and did not inform anyone; people thought he had died a natural death. Then the boy grew up, his intellect became complete, he benefited from admonitions and guidance, migrated to (the tribe of) Āl al-ʿĀmirī, felt remorse and fear, and wanted to free himself [from the guilt] and repent to Allah. He disclosed his story to me, while he is still concealing it from everyone else to this day, and he asked me for a ruling.
