Mírzá ʻAbbás Núrí

Mírzá Buzurg prospered in the service of the State, until the death of Fath Ali Shah, and the rise of Muhammad Sháh (reigned 1834–48), under whose grand vizier, Haji Mirza Aqasi, he lost his position and much of his considerable wealth.

One reason which prompted his enmity was Mírzá Buzurg's particular friendship with the Qá'im-Maqam, Mirza Abu'l-Qasim of Farahan.

Mírzá Buzurg wrote letters condemnatory of Hajji Mirza Aqasi, which the Prime Minister eventually encountered, and retaliated with force.

A document exists in the handwriting of Muhammad Shah himself, commending and praising the services rendered by Mírzá Buzurg in this capacity.

Then, he began to disturb the relationship between Mírzá Buzurg and his last wife, Ziya us-Saltana, the daughter of Fath Alí Shah.

He was forced to sell a part of his properties and mortgage others, including the complex of houses in Tehran in which he and his family resided.

In the end, Mírzá Buzurg was obliged to sell, once again, his complex of houses in Tehran, and part with the valuable carpets and other furnishings which they contained.

After the storms subsided, Mírzá Buzurg made an effort to regain the houses which he had had to sell under duress 'for a negligible sum'.

A document exists in the handwriting of Baháʼu'lláh, drawn up for the purpose of eliciting from those in the know their testimony to the fact that the sale of the houses had taken place under unlawful pressure.
