Talking in a TV programme, he said armed anti-sate activities in Pakistan were against religious teachings.
Maulana Fazl also said that Taliban had been involved in attacks on him.
Meanwhile, Rustam Shah Mohmand, a member of the government’s negotiating committee, said some rivals of the Taliban wanted to sabotage the peace talks.
Talking to reporters, he said the Taliban had dissociated themselves from the recent bomb attacks and indicated that they were ready for a ceasefire.
He said the dialogue would only be held with the Tehreek-i-Taliban Pakistan within the ambit of the constitution and no area would be surrendered to any group.
Mr Mohmand said the talks process should continue despite difficulties.
Talking to a TV channel, Maulana Samiul Haq, chief of the TTP’s negotiating team, said all groups of the Taliban had supported the dialogue, but some elements wanted to derail the efforts for peace through their terrorist activities.
He said proposals for a ceasefire had been given by both sides and he was hopeful of an early agreement.
Prof Muhammad Ibrahim, another TTP negotiator, said a meeting between the government committee and leaders of the Taliban could be arranged.
