Most controversially, in 2008 he hosted a show in which Muslim clerics declared that members of the Ahmadi community, a vulnerable religious minority, were “deserving of death.” Forty-eight hours later, two Ahmadi leaders, one of them an American citizen, had been shot dead in Punjab and Sindh Provinces.

Many media critics held Mr. Hussain partly responsible, and the show so appalled American diplomats that they urged the State Department to sever a lucrative contract with Geo, which they accused of “specifically targeting” Ahmadis, according to a November 2008 cable published by WikiLeaks.

Now, Mr. Hussain casts himself as a repentant sinner. In his first Ramadan broadcast, he declared that Ahmadis had an “equal right to freedom” and issued a broad apology for “anything I had said or done.” In interviews, prompted by his own management, he portrays himself as a torchbearer for progressive values.

“Islam is a religion of harmony, love and peace,” he said, as he waited to have his makeup refreshed. “But tolerance is the main thing.”

IN some ways, Mr. Hussain is emblematic of the cable television revolution that has shaped public discourse in Pakistan over the past decade. He was the face of Geo when the upstart, Urdu-language station began broadcasting from a five-star hotel in Karachi in 2002. Then he went political, winning a parliamentary seat in elections late that year. The station gave him a religious chat show, Aalim Online, which brought together Sunni and Shiite clerics. The show received a broad welcome in a society troubled by sectarian tensions; it also brought Mr. Hussain to the attention of the military leader Gen. Pervez Musharraf, who was reportedly touched by its content. In 2005, General Musharraf appointed him junior minister for religious affairs, a post he held for two years.
