There have been daily confrontations between Palestinians hurling rocks and Israeli police using stun grenades since the detectors were placed at the entrance to the shrine, known to Muslims as the Noble Sanctuary and to Jews as Temple Mount, on Sunday, after the killing of two Israeli policemen.
Palestinians have been refusing to enter the compound all week in protest at the metal detectors.
Thousands of Muslim worshippers traditionally attend Friday prayers at Al Aqsa.
Speculation had been mounting that Israeli Prime Minister Benjamin Netanyahu might order the metal detectors removed before this week's prayers.
Members of Netanyahu's right-wing coalition have been pressuring him to leave the metal detectors in place and "ensure security" at the site. Meanwhile, Presidential Spokesperson İbrahim Kalın said developments regarding the al-Aqsa mosque were disrupting and unacceptable.

Al-Aqsa Mosque is the third holiest site for Sunni Muslims, after the cities of Mecca and Medina.
The events come in wake of an attack by a gunman that killed two Israeli policemen outside the compound.
Palestinian President Mahmoud Abbas protested the metal detector installation to the USA administration, calling on President Donald Trump's son-in-law and adviser Jared Kushner to push the president to "intervene urgently".
He said Mr Abbas discussed the growing tensions in Jerusalem in a phone call with Donald Trump's Middle East adviser and son-in-law, Jared Kushner.
