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 Messenger (ﷺ) upon it.

حَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ - حَدَّثَنِي أَبُو حَازِمٍ عَنْ عُبَيْدِ اللَّهِ بْنِ مِقْسَمٍ، أَنَّهُ نَظَرَ إِلَى عَبْدِ اللَّهِ بْنِ عُمَرَ كَيْفَ يَحْكِي رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏

‏ يَأْخُذُ اللَّهُ عَزَّ وَجَلَّ سَمَوَاتِهِ وَأَرَضِيهِ بِيَدَيْهِ فَيَقُولُ أَنَا اللَّهُ - وَيَقْبِضُ أَصَابِعَهُ وَيَبْسُطُهَا - أَنَا الْمَلِكُ ‏

‏ حَتَّى نَظَرْتُ إِلَى الْمِنْبَرِ يَتَحَرَّكُ مِنْ أَسْفَلِ شَىْءٍ مِنْهُ حَتَّى إِنِّي لأَقُولُ أَسَاقِطٌ هُوَ بِرَسُولِ اللَّهِ صلى الله عليه وسلم
