"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.
In another development on Monday, the Commonwealth gave Pakistan 10 days to restore its constitution and ease other emergency measures or face suspension from the 53-nation bloc.
It demanded that Musharraf step down as army chief and release those arrested, as well as ease media curbs.
Don McKinnon, the secretary-general, said that if Musharraf doess not meet its demands by November 22, when Commonwealth ministers meet on the eve of a summit of the bloc in Uganda, then Pakistan will be suspended.
