"Under the current circumstances it is very difficult to expect there would be fair elections in the country," he told Associated Press Television News.
"Within the next week there will be meetings and we will finally decide whether to go for elections or agitation."
Musharraf said on Sunday that there would be no time limit on emergency rule, which he imposed on November 3.
He also said he would take the oath of office for another term as a civilian and relinquish his post as army chief, without giving a precise date.
On Sunday, Sharif told Al Jazeera that Musharraf's clampdown on Pakistan's judiciary also needed to be addressed.
"Before we talk about the elections, we should make sure that the judiciary in Pakistan will go back to the way it was before November 3, before declaring the state of emergency. And this is the most important matter," he said.
"That is why the elections will be useless if they are carried out in the absence of law and without the participation of all parties. Otherwise, the situation will become complicated."
Under the state of emergency, key figures in the judiciary have been sacked or detained, including Iftikhar Chaudhry, Pakistan's chief justice.
The press in Pakistan on Monday joined criticism of Musharraf, saying that elections would be undermined if held under emergency rule.
"[Musharraf's] new scheme as announced casts a doubt on the credibility of the forthcoming elections," Dawn, Pakistan's oldest English language daily newspaper, said.
The Nation, another English language newspaper, on Monday said: "It would be hard to dispel the impression of a stage-managed affair without a free media, the freedom to hold meetings, take out processings and do canvassing - the traditional modes of electioneering."
However, Condoleeza Rice, US secretary of state, said she was concerned that Musharraf had not set a time limit for the end of emergency law.
"It's not a perfect situation," she said on Monday.
