Baha'u'llah sold off the properties without Azal's consent

The Bab explicitly appointed Subh-i-Azal (Mirza Yahya) as his deputy and successor in 1850, leaving behind a sealed will and testament declaring that no new Manifestation would appear for at least 2000 years. Baha'u'llah violated this appointment by proclaiming himself to be "He Whom God Shall Make Manifest" only a few years after the Bab's death. This was a direct betrayal of the Bab's explicit instructions and a deliberate attempt to seize leadership of the Babi community for personal ambition.

While Subh-i-Azal was preparing for exile, Baha'u'llah sold their father's properties and inheritance in Tehran without his consent, leaving Azal in severe financial hardship. Baha'u'llah then engaged in systematic character assassination, portraying Subh-i-Azal as "the living example of evil and greed," a "puppet," and a "liar." Baha'u'llah appropriated half of the government allowance (pension) intended for the Babi community and used his greater social influence to isolate Subh-i-Azal during their exiles in Baghdad, Istanbul, and Edirne.

Azali sources hold Baha'u'llah responsible for the deaths of prominent Babis who remained loyal to Subh-i-Azal, including the Bab's cousin Mirza Ali Akbar and the scholar Dayyan. Baha'u'llah sought to poison Subh-i-Azal during the conflict in Edirne and, after the Ottoman authorities separated the two brothers, several Azalis sent to Akka with Baha'u'llah were murdered soon after their arrival. This sustained campaign of marginalization forced Subh-i-Azal into a lonely, ascetic exile in Cyprus while Baha'u'llah's movement eclipsed the original Babi faith.
