"A Jew came to the Prophet ﷺ and said: 'O Muhammad! Allah will seize the heavens upon a finger, the mountains upon a finger, the earths upon a finger, and the rest of creation upon a finger. Then He says: 'I am the King.'" He said: 'So the Messenger of Allah ﷺ laughed until his molars were visible. He said: "They made not a just estimate of Allah such as is due to Him (39:67)." (Using translation from Tirmidhī 3238)
أَنَّ يَهُودِيًّا أَتَى النَّبِيَّ ﷺ فَقَالَ يَا مُحَمَّدُ إِنَّ اللهَ يُمْسِكُ السَّمَاوَاتِ عَلَى إِصْبَعٍ وَالْأَرَضِينَ عَلَى إِصْبَعٍ وَالْجِبَالَ عَلَى إِصْبَعٍ وَالْخَلَائِقَ عَلَى إِصْبَعٍ وَالشَّجَرَ عَلَى إِصْبَعٍ ثُمَّ يَقُولُ أَنَا الْمَلِكُ فَضَحِكَ رَسُولُ اللهِ ﷺ حَتَّى بَدَتْ نَوَاجِذُهُ وَقَالَ {وَمَا قَدَرُوا اللهَ حَقَّ قَدْرِهِ} [الأنعام 91] قَالَ يَحْيَى وَقَالَ فُضَيْلٌ يَعْنِي ابْنَ عِيَاضٍ تَعَجُّبًا وَتَصْدِيقًا لَهُ
