Since the time of Bahá’u’lláh dissimulation has been forbidden for Bahá’ís but Abdu’l-Bahá attended the mosque in Akka!!!

It is important to note at this juncture that although Shoghi Effendi did not find it appropriate in his day, there had been great wisdom in Abdu’l-Bahá’s attendance at the mosque during His Ministry. At the time of Bahá’u’lláh’s arrival, the people of Akka considered a man who did not attend a mosque or a church to be an infidel. The Faith had neither formulated its teachings and laws, nor was its true identity known to the inhabitants of the Holy Land. It had been presented to the population as a misguided sect of unbelievers. In these circumstances, refusal to go to the mosque would have stigmatized Bahá’u’lláh and His companions as infidels. By attending the mosque they came to be regarded in the eyes of the public as believers in God. One of the useful by-products of attending the mosque was that Abdu’l-Bahá established a marvellous relationship with the people, and in time emerged, in the words of an admirer, as the ‘Master of Akka’.

Attending a mosque is exactly what a MUSLIM, not a Baha'i, would do. And yet less than a century later, the Universal House of Justice would teach this:

"...it was permissible in Shi’ih Islam for believers to deny their faith in order to escape persecution. since the time of Bahá’u’lláh such an action has been forbidden for Bahá’ís. We do not defend our Faith by the sword, as was permissible in Islam, but Bahá’ís have always held to the principle that when challenged they should `stand up and be counted’, as the modern expression is, and not purchase their safety by denying that which is most important to them in this world and the next. The principle is well known to the Iranian Bahá’ís and is upheld by the overwhelming majority of them when the penalty is martyrdom."
