Egypt plans to lift a three-month state of emergency and curfew on Tuesday, two days earlier than expected, two government sources and a security source said.
Egypt's army-backed authorities announced the nightly curfew on August 14, when security forces forcibly ended the two main sit-ins by supporters of ousted Islamist President Mohamed Morsi in Cairo, prompting waves of violence in which hundreds of people have been killed.
The state of the emergency allowed the authorities to make arrests without warrants and gave security officials the right to search people's homes.
The government's decision, the security source said, came after a court ruling that the state of emergency, that includes the curfew from 1 am to 5 am, expired on Tuesday.
The cabinet said in a statement it was "committed to execute the court ruling and is waiting to receive a copy of the ruling to execute it."
Hundreds of pro-Morsi supporters have been staging almost daily protests against the army since they deposed him in July.
Egyptian authorities have arrested thousands of Islamist activists and Morsi supporters in the past three months.
Many blamed the curfew, which initially started at 7 pm but has been reduced over the weeks, on dampening trade in central Cairo at a time when the government is desperately trying to create jobs and boost an economy that has been badly hit by the turmoil.
