Amir narrated, and he also mentioned Qays: Sayyiduna Ibn Mas'ud (may Allah be pleased with him) would narrate for a whole month without saying: I heard the Messenger of Allah (peace and blessings be upon him). And whenever he said: "I heard the Messenger of Allah (peace and blessings be upon him)," he would add: "This, or something like it, or close to it," while he was trembling.
