Abu Ubaydah said: A whole year would pass over Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) in which he would not narrate from the Messenger of Allah (peace and blessings be upon him). Then one day he narrated a hadith while we were with him, and said: "Like this, or close to this."
