Mustadrak al-Hakim — Hadith 1776

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) threw pebbles at the Jamrah that is near the mosque of Mina, he would throw seven pebbles at it, saying the takbir with each pebble. Then he would move ahead of it, stand facing the qiblah, raise his hands and supplicate, and he would stand for a long time. Then he would come to the second Jamrah and throw seven pebbles at it, saying the takbir with each pebble. Then he would descend to the left side of the valley, and stand facing the qiblah with his hands raised. Then he would come to Jamrat al-Aqabah and throw seven pebbles at it, saying the takbir with each pebble. Then he would turn back and would not stand there. Al-Zuhri said: I heard Salim bin Abdullah narrate the same from his father from the Prophet (peace and blessings be upon him), and Ibn Umar also used to do the same.
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it!
