From Sahih Muslim (Hadith 7052):
Abdullah b. Miqsam reported that he saw Abdullah b. Umar as he narrated Allah's Messenger (ﷺ) as saying:Allah, the Exalted and Glorious, would take in His hand His Heavens and His Earth, and would say: I am Allah. And He would clench His fingers and then would open them (and say): I am your Lord. I saw the pulpit in commotion from underneath because of something (vib-ating) there. And (I felt this commotion so much) that I said (to myself): It may not fall with Allah's Massenger (ﷺ) upon it
