“The lower level are listening to the religious people,” he said.

Indeed, the Pakistan of today, and the brand of Islam much of the nation has embraced, is barely recognizable even to many educated Pakistanis older than the Zia generation. Among them is Athar Minallah, 49, a former cabinet minister and one of the leaders of the lawyers’ protest campaign against Gen. Pervez Musharraf in 2007 and 2008.

Mr. Minallah studied law at Islamic University in Islamabad from 1983 to 1986, and the first lesson any student learned in his day was that the preservation of life was a pillar of Islamic law, he said.

But under General Zia in the 1980s, the government began supporting Islamic warriors to fight the Soviet occupation of Afghanistan and the Indian control of Kashmir, and the syllabus was changed to encourage jihad. The mind-set of students and graduates changed along with it, Mr. Minallah said.

That change is now no more apparent than among the 1,000 lawyers from the capital, Islamabad, and the neighboring city of Rawalpindi, who have given their signed support for the defense of Mr. Qadri, who has been charged with murder and terrorism.

Their leader is Rao Abdur Raheem, 30, who formed a “lawyers’ forum,” called the Movement to Protect the Dignity of the Prophet, in December. The aim of the group, he said, was to counter Mr. Taseer’s campaign to amend the nation’s strict blasphemy laws, which promise death for insulting the Prophet Muhammad.

In interviews, Mr. Raheem and six of his colleagues insisted they were not members of any political or religious party, and were acting independently and interested only in ensuring the rule of law.

All graduates of different Pakistani universities, they insisted they were liberal, not religious conservatives. Only one had religious training. They said they had all taken part in the lawyers’ protest campaign in 2007 and 2008, and that they were proud that the movement helped reinstate the chief justice.
