Sahih Muslim Book 39, Hadith Number 6705.
Chapter : Description of the day of judgement, paradise and hell.
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.
