[4] His brother Talib bin Ali would become an effective and determined leader in the imamate's revolt against the sultan of Muscat in the 1950s.

The British government favoured IPC's plan as it sought benefits from the expansion of the Sultanate's territory and considered oil discovery in Oman as a valuable insurance against the insecurity of other parts of the Middle East.

The British Political Agent believed that the only method of granting the oil company access to the interior was by assisting the sultan in occupying the Imamate.

The British government concluded that it is reluctant "in principle" to the use of force for the reason of avoiding international criticism that may lead to the calling of the British government before the United Nations Security Council but they executed anyway waging war for over 5 years between the two Head of Estate on the battle ground Jabel Akhdar (The Green Mountain) with over 2,000 martyrs losing their lives.

[15][16] The restrengthening of the imamate's forces materialized when a number of the interior villages were recaptured, including Bilad Sayt, on 14 June 1957.

[17] The war lasted 5 years until the SAF, with much difficulty and following direct support of soldiers from the British Special Air Service, 1st Battalion of the Cameronions, a troop of the 15/19 Hussars, RAF fighter jets and a squadron of Ferret armoured cars,[17] put down the Jebel Akhdar War in 1959,[13] and Imam Ghalib al-Hinai managed to escape to Saudi Arabia.

[18] Imam Ghalib delegated his brother, Talib al-Hinai, who was the wali (governor) of Rustaq, and Suleiman bin Hamyar, who was the wali (governor) of Jebel Akhdar,[19] to present the issue to the Arab League and the United Nations in order to seek recognition and claim legitimacy of the imamate of Oman.

[18] In August 1959, the UN Security Council voted by a narrow margin not to consider a request for an urgent meeting to discuss 'British aggression against' an independent imamate of Oman.
