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. (Using translation from Muslim 2788b)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ وَهُوَ عَلَى الْمِنْبَرِ يَأْخُذُ اللهُ سَمَوَاتِهِ وَأَرَضِيهِ بِيَدَيْهِ ثُمَّ يَقُولُ أَنَا اللهُ وَيَقْبِضُ بَيْنَ أَصَابِعِهِ وَيَبْسُطُهَا أَنَا الرَّحْمَنُ أَنَا الْمَلِكُ حَتَّى نَظَرْتُ إِلَى الْمِنْبَرِ يَتَحَرَّكُ مِنْ أَسْفَلِ شَيْءٍ مِنْهُ حَتَّى إِنِّي لَأَقُولُ أَسَاقِطٌ هُوَ بِرَسُولِ اللهِ ﷺ؟
