Sahih Bukhari | Volume 2 | Hadith Number 808
Narrated by Salim bin Abdullah
'Abdullah bin 'Umar used to do Rami of the Jamrat-ud-Dunya with seven small pebbles and used to recite Takbir on throwing each stone. He, then, would proceed further till he reached the level ground, where he would stay for a long time, facing the Qibla to invoke (Allah) while raising his hands. Then he would do Rami of the Jamrat-ul-Wusta similarly and would go to the left towards the level ground, where he would stand for a long time facing the Qibla to invoke (Allah) while raising his hands. Then he would do Rami of the Jamrat-ul-'Aqaba from the middle of the valley, but he would not stay by it. Ibn 'Umar used to say, "I saw Allah's Apostle doing like that."
