Muhammad ibn al-Muthanna narrated to us, Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, he said: I heard 'Abdah ibn Abi Lubabah narrating from Zirr ibn Hubaysh, from Ubayy ibn Ka'b, who said: Ubayy said concerning the Night of Decree: By Allah, I indeed know it, and most of my knowledge is that it is the night which the Messenger of Allah, peace and blessings be upon him, commanded us to stand in prayer—it is the night of the twenty-seventh. And Shu'bah only doubted in this wording: it is the night which the Messenger of Allah, peace and blessings be upon him, commanded us to observe. He said: And a companion of mine narrated it to me from him.
