Badri-Jan, the sister of the murdered Mirza Rida-Quli, sought an interview with Ahmad Big Tawfiq and there accused Baha’u’llah of instigating the murders

A year after the murder of the Azalis, the Governor of ‘Akka, who had remained ill-disposed towards the exiles, was dismissed from office and replaced by Ahmad Big Tawfiq, a wise and compassionate man: Soon after his installation as Governor, Badri-Jan, the sister of the murdered Mirza Rida-Quli, sought an interview with Ahmad Big Tawfiq and there accused Baha’u’llah of instigating the murders and of plotting to rule over all, the kings of the world included. To back up her allegations, she left with the Governor a copy of the Suriy-i-Muluk and some other writings of Baha’u’llah.

Badri-Jan’s efforts backfired. The Governor was so impressed by these writings that he sought out ‘Abdu’l-Baha in order to learn more.

It was as a result of the repeated requests made by Ilyas ‘Abbud that Baha’u’llah consented to receive Ahmad Big Tawfiq. In this interview Baha’u’llah requested the Governor to review the cases of the Baha’is who were held in captivity. The Governor agreed and carefully reviewed each case. All those except the seven responsible for the murders were released in July of 1873.
