Musnad of Abdullah bin Mas'ood
‘Abdur-Rahman bin Yazeed said: I saw ‘Abdullah go to the bottom of the valley, he put the Jamrah on his right and turned to face the House, then he stoned it with seven pebbles, saying takbeer after each throw. Then he said: This, by the One besides Whom there is no other God, is the place where the one to whom Sooratal Baqarah was revealed stood.
