Bayhaqi 4790 — Witr with one rak'ah, and one who permitted praying

Al-Muttalib bin Abdullah al-Makhzumi (may Allah have mercy on him) said that a man came to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and asked: "How should I pray witr?" Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: "Pray one rak'ah of witr." He said: "I was afraid that people would say: This is al-butayra' (the cut-off prayer)." The narrator said that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) asked: "Do you want the Sunnah of Allah and His Messenger (peace and blessings be upon him)? This is the way of Allah and His Messenger (peace and blessings be upon him)."
