The Taarikh writes as revived from the Isdhoo loamaafanu: " next Friday a ship will arrive, whereon I shall sail for Makkah. The day named verily a vessel anchored at Malé. The Sultan, having performed the Jumu'ah at the mosque, hurried to the seashore and embarked in the vessel without attendants or provisions. Forwith the ship passed from sight as suddenly as lightning " On the disappearance of his uncle, Muthey Kalaminja took over the throne of the Maldives and ruled as the sultan from 1166 according to the Raadhavalhi.
