Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: A man addressed the Prophet Muhammad (peace be upon him) in a loud voice while I was between them. He asked: How should the prayer at night be performed? The Prophet Muhammad (peace be upon him) replied: It should be performed two by two, and when you fear that dawn is near, then perform one rak'ah and two prostrations before the break of dawn.
