The Sermon on the day of Sacrifice, throwing Pebbles on the tashriq days, and taking Farewell of the Ka`ba - Section 1 — Mishkat al-Masabih 2660

Wabara said he asked Ibn ‘Umar when he should throw pebbles at the jamras, to which he replied, “Throw them when your imam does so.” He repeated the question and received the reply, “We used to wait for the proper time, and when the sun passed the meridian we threw them.” Bukhari transmitted it.
