Aziz's controversial statement and the mosque's resurgence comes at a crucial time when the country is battling militancy and is in the middle of a national debate over whether to negotiate with the terrorists.
The report says that clerics of the mosque "which has burnished its credentials as a citadel of Islamist revolt" are exploiting the government's failure to offer an alternative vision of Pakistan's future.
Seven years ago, the mosque was under in the throes of a pitched battle with the authorities.
Aziz who tried to escape the siege under the cover of a burqa, was captured and paraded by the intelligence services on national television. The cleric's brother and his elderly mother died in the firefight.
After the siege was over, Aziz was charged with murder, abduction, arson and terrorism. The court had blamed even former military ruler General Pervez Musharraf for the incident.
Yet within a couple of years, the mosque was reconstructed with generous donations and Aziz was back in business.
