Musa tried to assassinate his father in the coup, but Rabi'a managed to escape and fled to the Emirate of al-Uyaynah, where Hamad ibn Hassan gave him refuge.
His father Mani' lived with his relatives in the east of the peninsula and settled in a place called al-Diriyah, near al-Qatif (not to be confused with Diriyah, the capital of the first Saudi state).
Musa not only wanted to gain political control of Diriya, but also considered his father a threat to his own interests, so after taking power he decided to kill him.
Uthman ibn Bishr narrates in one of his works on Najdi history the following: "Rabi'a became famous in Najd, as his kingdom expanded and he fought against the Yazid clan.
Musa tried to kill his father Rabia, who badly wounded fled and was welcomed by Hamad bin Hasan Ibn Touq, emir of Al-Uyaynah, who honored and protected him for a favor he had previously done him.
