Qais bin Ahmad Al Busaidi in the context of Ahmad bin Sa'id Al-Busaidi

Sayyid Saïd bin Sultan al-Busaidi (Arabic: سعيد بن سلطان, Saʿīd bin Sulṭān, Swahili: Saïd bin Sultani) (5 June 1791 – 19 October 1856) was Sultan of Muscat and Oman, the fifth ruler of the Al Bu Said dynasty from 1804 to 4 June 1856. His rule began after a period of conflict and internecine rivalry of succession that followed the death of his father, Sultan bin Ahmad, in November 1804. He is often referred to as the Lion of Oman (أسد عمان), as one of the greatest Omani sultans.

Said's uncle Qais bin Ahmad finally agreed to Said's primacy after Said had killed his cousin, Badr bin Saif, a pretender to the throne. Said is noted for moving his capital to Zanzibar, where it remained during the time when the Omani Empire reached the zenith of its power and wealth.

Salim bin Sultan was joint Sultan of Oman with his brother Said bin Sultan, ruling between 1804 and 1806.

Salim bin Sultan was son of Sultan bin Ahmad, who ruled Oman from 1792 to 1804.Sultan bin Ahmad died in 1804 on an expedition to Basra. He appointed Mohammed bin Nasir bin Mohammed al-Jabry as the Regent and guardian of his two sons, Salim bin Sultan and Said bin Sultan.Sultan's brother Qais bin Ahmad, ruler of Sohar, decided to attempt to seize power. Early in 1805 Qais and his brother Mohammed marched south along the coast to Muttrah, which he easily captured. Qais then started to besiege Muscat.Mohammed bin Nasir tried to bribe Qais to leave, but did not succeed.
