Sunan Ibn Majah Book 25, Hadith 151
It was
narrated that Ibn ‘Umar stoned ‘Aqabah Pillar, but he did not
stay there, and he mentioned that the Prophet (ﷺ) had done
likewise.
“I saw the Prophet (ﷺ) on the Day of Sacrifice, at ‘Aqabah Pillar. He went to the interior of the valley and threw seven pebbles, saying Takbir with each pebble, then he departed.”
Another chain reports a similar hadith.
“When the Messenger of Allah (ﷺ) had stoned ‘Aqabah Pillar, he would continue on, and would not stay there.”
