Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Nafi' that when Hazrat Ibn Umar (may Allah be pleased with them both) performed the Rami, he kept the Jamrah in front of him and supplicated to Allah Almighty, raising his hands. We also raised our hands with him. Then he did not lower his hands until, due to the crowd, pushing and shoving began, so we lowered our hands, but he remained as he was.
