Hazrat Salih bin Hayan (may Allah have mercy on him) narrates that Hazrat Ibn Buraidah (may Allah be pleased with him) said: Regarding this verse of the Qur'an (__QUR_N__: "They said to those who were given knowledge, 'What did he say just now?'"), those people ask those who have been given knowledge, "What did the Messenger of Allah (peace and blessings be upon him) just say?" By this, Hazrat Abdullah bin Mas'ud (may Allah be pleased with him) is meant.
