حَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، قَالَ سَمِعْتُ إِبْرَاهِيمَ، يَقُولُ سَمِعْتُ عَلْقَمَةَ، يَقُولُ قَالَ عَبْدُ اللَّهِ جَاءَ رَجُلٌ مِنْ أَهْلِ الْكِتَابِ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ يَا أَبَا الْقَاسِمِ إِنَّ اللَّهَ يُمْسِكُ السَّمَوَاتِ عَلَى إِصْبَعٍ وَالأَرَضِينَ عَلَى إِصْبَعٍ وَالشَّجَرَ وَالثَّرَى عَلَى إِصْبَعٍ وَالْخَلاَئِقَ عَلَى إِصْبَعٍ ثُمَّ يَقُولُ أَنَا الْمَلِكُ أَنَا الْمَلِكُ ‏.‏ قَالَ فَرَأَيْتُ النَّبِيَّ صلى الله عليه وسلم ضَحِكَ حَتَّى بَدَتْ نَوَاجِذُهُ ثُمَّ قَرَأَ ‏{‏ وَمَا قَدَرُوا اللَّهَ حَقَّ قَدْرِهِ‏}‏

Abdullah reported that a person from the People of the Book came to Allah's Apostle (may peace he upon him) and said:Abu al-Qasim, verily, Allah holds the Heavens upon one finger and the earths upon one finger and the trees and moist earth upon one finger and in fact the whole of the creation upon one finger and then say: I am the King. I am the King. And he (the narrator) further said: I saw Allah's Messenger (ﷺ) smiling until his front teeth became visible and then he recited the verse: "And they measure not the power of Allah with His true measure" (39:)
