Abd al-Rahman bin Yazid (may Allah have mercy on him) narrated: I saw Sayyiduna Ibn Mas'ud (may Allah be pleased with him) stone the Jamrah, in such a way that Mina was on his right and Makkah on his left. He threw seven pebbles at it, then said: "This is the standing place of the one upon whom Surah al-Baqarah was revealed."
