Sahih Muslim Book 39, Hadith Number 6705.

Abdullah b. Miqsam reported that he saw Abdullah b. Umar as he narrated Allah’s Messenger (may peace be upon him) 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 (vibrating) there. And (I felt this commotion so much) that I said (to myself): It may not fall with Allah’s Messenger (may peace be upon him) upon it.
