Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrated about the Prophet (peace and blessings be upon him): In the witr he would recite Surah al-A'la, Surah al-Kafirun and Surah al-Ikhlas.
Imam al-Bazzar and Imam al-Tabarani in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat recorded this narration; its chain contains a narrator, Sa'id bin Sinan, who is da'if (weak).
