Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Whoever offers the Isha prayer in congregation and then offers four rak'ahs before going out of the mosque, it will be equal to Laylat al-Qadr (the Night of Decree)."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat, and its chain contains a weak narrator who has not been accused of lying.
