Back in August 1868 the government of the Sultan of the Ottoman Empire sentenced Baha’u’llah and His half -brother Subh-i-Azal to exile.. sending Subh-i-Azal to Farmagusta, Cyprus and sending Baha’u’llah to the prison fortress of Akka.. in order to keep an eye on both a strategy was devised to send some of the adherents of each to supposedly spy and report on the prisoners.
So four followers of Baha’u’llah were exiled to Cyprus and four Azalis were sent to Akka..
Among the four sent to Cyprus was the well known calligrapher Mishkin Qalam “.. The Baha’is on Cyprus were not happy with the situation and as soon as they could they returned to the Holy Land to gain the presence of Baha’u’llah.
The Azalis sent to Akka according to the Baha’is kept track of who went to see Baha’u’llah and tried to foment trouble and this led some “misguided Baha’is” “without the authorization of Baha’u’llah to murder the Azalis”..
23 Jan 1872 Murder of Siyyid Muhammad (the one who had constantly manipulated Mirza Yahya into his cowardly acts), Aqa Jan Big and another companion Covenant-breaker in ‘Akka in retaliation for their persecutions. Bahá’u’lláh had forbidden any act of retaliation, but seven of His tormented companions succumbed. An army of men descended upon the Bahá’ís. The seven guilty men were confined for several years. The remainder were confined for six months. The distress caused to Bahá’u’lláh of this event was immeasurable: “That which can make Me ashamed is the conduct of such of My FOLLOWERS as profess to love Me”.
(Same kind of story is narrated by the Baha’is regarding the execution attempt on the Shah of Iran on 28th August 1852 by some Babis / Baha’is)
As to Subh-i-Azal he was left alone by the Baha’is sent with his family and was later isolated by his own followers to a great degree..He passed on in 1912 on the island of Cyprus.
