…in a Tablet He [‘Abdu’l-Baha] referred to the "irrefutable command that the Blessed Perfection hath given" in His Tablets, namely, "that the believers must obey the kings with the utmost sincerity and fidelity, and He hath forbidden them [the believers] to interfere at all with political problems. He hath even prohibited the believers from discussing political affairs."
