Narrated 'Aishah:The Messenger of Allah (ﷺ) performed the obligatory circumambulation of the Ka'bah at the end of the day of sacrifice after he had offered the noon prayer. He hen returned to Mina and stayed there during the tashriq days and he threw pebbles at the jamrahs when the sun declined. He threw seven pebbles at each of the jamrahs, uttering the takbir (Allah is most great) at the time of the throwing the pebble. He stood at the first and the second jamrah, and prolonged his standing there, making supplications with humilation. He threw pebbles at the third jamrah but did not stand there
