Sunan Ibn Majah, Chapter: The Book of the Sunnah

"I heard the Messenger of Allah (saw) say, when he was on the pulpit 'The Compeller will seize the heavens and the earths in His Hand' and he clenched his fist and began to open and close it. Then He will say: "I am the Compeller! Where are the tyrants? Where are the arrogant?"' He said, the Messenger of Allah (saw) was turning to his right and to his left, until I saw the pulpit moving from below and I thought: 'What if it falls with the Messenger of Allah (saw) on it?'" (Sahih)
