Ezziyeh Nouri, Bahaullah's sister and of the supporters of Sobhi Azal reveals the physical pains of his brother Bahaullah addressing Abdul Baha.

"For more years, your father has been afflicted by hernia and shaking palsy. He couldn't cure himself. How can he cure people's physical pains? The physician who cures people's pain is sickly!!!! (Tanbihunnaemin- p.38)

Shoqi Effendi is also saying about this fact:

"In order to revive his forged and to re-establish his lost and dreamed chairmanship, Mirza Yahya thought to make the Blessed beauty poisonous. Addition he asked the blessed Beauty about the specifications of several spices and plants because he know the Blessed beauty was familiar with medical characteristics and issues. So, he invited the Blessed Beauty to his house as an old custom and poured some poisonous materials in to his tea to make him poisonous. He became sick and was hospitalized for a month He had a fever; so he was afflicted by shaking pulsy to the end of his life…" (Badi'a century- Shoqi Effendi)

Also, one of the Baha'is has confessed this fact in his book that:

"Azal was successful to get Bahaullah into many problems. He tried to make Bahaullah poisonous by pouring poison into his food. It caused his hands to be afflicted by shaking pulsy in his rest of life." (A short speech about the Baha'i religion-Mojan Momen- p. 286)

The interesting note is that the physician who is claimed for curing the people's pains is sickly. He is also the Baha'is god!
