Abdur Rahman bin Yazid says that during Hajj I was with Sayyiduna Ibn Mas'ud (may Allah be pleased with him). When he reached near Jamrah Aqabah, he said, "Give me some pebbles." I gave him seven pebbles. Then he said to me, "Hold the camel's rein." Then, stepping back, he threw seven pebbles at Jamrah Aqabah from the bottom of the valley while still mounted, and with each pebble he said takbeer and kept supplicating, "O Allah! Make it a Hajj Mabroor and forgive the sins." Then he said, "That personality also stood here upon whom Surah Al-Baqarah was revealed."
