Musannaf Ibn Abi Shaybah 6985 — Those who prayed witr with one rakah

Ibn Sirin said: Sayyiduna Ibn Mas'ud and Sayyiduna Hudhayfah (may Allah be pleased with them both) spent the night talking at the house of al-Walid bin Uqbah. Then they came out talking with each other, and when morning came, each of them prayed one rak'ah.
