Muhammad Ibráhím Amir, known for his bravery and good looks, showed great courage as one of the defenders of the Khájih Fort in support of Vahid. After the first upheaval he managed to escape. During the second upheaval he and his brothers joined Sardar's forces positioned on the Balataram Mountains, south of Nayriz. He received the surname Amir, meaning Commander, from Bahá'u'lláh.

The governor had been quite anxious to capture them since they were the ones who during an earlier incident captured the two sons of the governor's brother. They had brought the boys as prisoners to Vahid in the Khájih Fort. Vahid forgiving the captives released them to return to the governor with a message. As soon as gates of the fort opened, the enemies thinking the two were Bábís, fired fatal shots at them.

After the second upheaval Amir and his brothers were captured but managed to get away in a daring escape. The soldiers tied their hands behind them and were carrying them to the governor's mansion. Somehow Amir managed to untie his hands, grab a knife from one of the guards, fight the guards, untie his brothers and rescue them. Once again, they all managed to escape and take cover in the mountains.

Amir travelled to Baghdad and became a follower of Bahá'u'lláh. He stayed with Bahá'u'lláh for the rest of his life. Abdu'l-Baha gives tribute to him in the book “Memorials of the Faithful”. Mr. Ali Nakhjavani is his great grandson, through Amir's daughter, Bahiyyih.
