Muhammad Sayyid was Nawab of Arcot, who was a younger son (heir apparent) of Safdar Ali Khan.
However, the British East India Company at Madras firmly supported Muhammad Sayyid and proclaimed him as the Nawab of Arcot.
At the same time, Nizam ul Mulk Asaf Jah I came with a strong force and settled the claim in favor of Muhammad Sayyid.
During this period, Richard Benyon, the Governor of Fort St. George obtained the Nawab's firman in 1743 granting the villages of Perambur, Sadiankuppam, Ernavore, Pudubakkam and Vepery.
In the ensuing power struggle, it was Anwaruddin Khan who was confirmed as Nawab of Arcot (the first of the second dynasty) by Nizam of Hyderabad, Asaf Jah I.
