Addressing a large and fervent congregation of the people on Tehran University campus on Friday, Ayatollah Emami Kashani said, "These moves indicate deviation from Islam and also forming alliance with the global arrogance."
Ayatollah Emami Kashani urged the Bahraini government to bring the perpetrators of such insulting acts to justice.
Bahraini security forces raided Sheikh Qassim's house amid an ongoing crackdown on dissent on Monday.
Witnesses say regime forces even took photos of the ID cards of everyone who was inside the house in Diraz, West of the capital Manama.
The raid on the home of the spiritual leader of the opposition al-Wefaq group came just a few days after people voted in an alternative election held by the main opposition parties of Bahrain.
The opposition had boycotted the parliamentary elections which were held with a low turnout on the same day across the tiny kingdom.
Since mid-February 2011, thousands of protesters have held numerous demonstrations in the streets of Bahrain, calling for the Al-Khalifa royal family to relinquish power.
According to local sources, scores of people have been killed and hundreds arrested in the regime crackdown.
Bahrain has been severely criticized by human rights groups for its harsh crackdown on anti-government protesters which has claimed the lives of scores of people so far.
In June, the UN High Commissioner for Human Rights censured the Manama regime for human rights violations in the country.
