Abu Ishaq was asked: Did you mention, narrating from Abd al-Rahman bin Yazid, that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) in the Isha prayer, in the first rak'ah, recited: "They ask you about the spoils of war" [Surah al-Anfal: 1] until, on reaching "He is the best Protector and the best Helper" [Surah al-Anfal: 40], he bowed, and then in the second rak'ah he recited a surah from the Mufassal? He said: Yes.
