After the demise of King Somdej Phra Chao Song Dhum, Chao Phya Sheikh Ahmad Rattana Dhibodi retained his positions and influence during the reigns of King Somdej Phra Chao Cheta Thiraj (1628 - 1630), Phra Arthitiyawonse (who ruled for thirty-six days and was assassinated), and Kind Somdej Phra Chao Prasart Thong (1630 - 1654). All through this period of time, Siam was at peace with her neighbours. It was a time of prosperity and tranqulity, at least as far as external danger was concerned. The internal court intriques, however, continued.

It should be noted that, during the whole period of time, Sheikh Ahmad Qomi continued to conduct his trading enterprises and became an immensely wealthy man. He also acquired a sterlimg repatation of intergrity, honesty and loyalty to the Kings of Siam he served, while maintaining his own religion and nationality.

Chao Phya Sheikh Ahmad Rattana Dhibodi, served with utmost fidelity six Kings of Siam from King Somdej Phra Chao Song Dhum right up to the reign of King Somdej Phra Chao Narai Maharaj (King Narai the Great) (1656 - 1688).

Due to his outstanding efforts, achievements, and loyal devotion, he was finally rewarded, on this retirement, by the King Narai the Great, by being promoted Emeritus Minister of Civil Affairs with the title of Chao Phya Boworn Rajnayok.

He passed away shortly thereafter at the age of eighty - eight in 1659. His son Phya Apai Raja (Chuen) took over all the active offices his father held. Sheikh Ahmad Qomi's bequeath to his descendants, successors and followers was to serve the King and the Royal family with honesty, loyalty and intergrity - and never to meddle, encourage or participate in the plots and internal intriques of court life. This request became a commandment which was faithfully adhered to throughout the generations that followed, this in turn earned a universal respect for Sheikh Ahmad Qomi and his successors right up to the present time.
