The following is the full text of the message issued on April 20, 2013 by Ayatollah Khamenei the Leader of the Islamic Revolution on Ayatollah Rezvani's demise.
In the Name of Allah, the Beneficent, the Merciful
I would like to express my condolences to the honorable family of Ayatollah Rezvani, on the demise of Ayatollah Hajj Sheikh Gholam Reza Rezvani (may God bestow paradise on him) who was a great Islamic jurisprudent. I extend my condolences to all those who respect him and to his students. That great scholar was among the trustworthy students of Imam Khomeini (r.a.). He had certain responsibilities such as his responsibility in the Guardian Council. By Allah's favor, his services - which included cooperation with different organizations in illustrating fiqhi views of the Guardian Council - will be accepted by Allah the Exalted who will bestow paradise on him.
I ask Allah the Exalted to raise the position of this outstanding cleric.
Sayyid Ali Khamenei
