"A Jew passed by the Prophet ﷺ, so the Prophet ﷺ said: 'O you Jew! Narrate something to us.' So he said: 'What shall you say O Abul-Qasim, when Allah places the heavens upon this, the earths upon this, the water upon this, the mountains upon this, and the rest of creation upon this?'" - Muhammad bin As-Salt, Abu Ja'far (one of the narrators) indicated first with his little finger, then followed one by one until he reached his index finger - "So Allah, the Mighty and Sublime revealed: They made not a just estimate of Allah such as is due to Him (39:67)."
مَرَّ يَهُودِيٌّ بِالنَّبِيِّ ﷺ فَقَالَ لَهُ النَّبِيُّ ﷺ يَا يَهُودِيُّ حَدِّثْنَا فَقَالَ كَيْفَ تَقُولُ يَا أَبَا الْقَاسِمِ إِذَا وَضَعَ اللَّهُ السَّمَوَاتِ عَلَى ذِهْ وَالأَرَضِينَ عَلَى ذِهْ وَالْمَاءَ عَلَى ذِهْ وَالْجِبَالَ عَلَى ذِهْ وَسَائِرَ الْخَلْقِ عَلَى ذِهْ وَأَشَارَ أَبُو جَعْفَرٍ مُحَمَّدُ بْنُ الصَّلْتِ بِخِنْصَرِهِ أَوَّلاً ثُمَّ تَابَعَ حَتَّى بَلَغَ الإِبْهَامَ فَأَنْزَلَ اللَّهُ (وما قَدَرُوا اللَّهَ حَقَّ قَدْرِهِ )
