Musannaf Ibn Abi Shaybah 27905 — Awe of narrating from the Messenger

Amr bin Maymun said: I used to come to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) every Thursday. I never heard him say about any matter, "The Messenger of Allah (peace and blessings be upon him) said." Then one evening he said, "The Messenger of Allah (peace and blessings be upon him) said." At that he lowered his head. I looked at him, and he was standing with the buttons of his shirt undone; his eyes had filled with tears and his veins had swollen. He said: "Either less than that, or more than that, or close to that, or something like that."
