After the revolution, Sirous was threatened twice by the government of the Islamic Republic of Iran, part of the ongoing state-sanctioned persecution of Baháʼís, and in the winter of 1981 he was executed by firing squad, under the pretext of having committed espionage.

[1] As a teenager, he stopped attending school and entered the market trade due to financial difficulties and family hardship.

[1][2] Following the revolution, pressure continued to intensify on Sirous, often at the hands of the Islamic Revolutionary Guard Corps (IRGC), who bothered and threatened him.

He and his family survived multiple assassination attempts, scenes and false accidents planned and executed by the IRGC.

In addition to a poetry book which Sirous had written, he produced several volumes of books such as Barge Sabz (Green Leaf), Hayate Baha'I (Life of Baha'is), Gorg Dar Lebas (Wolf in a dress) and Ayame Dar Beh Dari (Nomadic Days).
