"Hammad bin Salamah narrated to us, from Thabit, from Anas, that the Prophet ﷺ recited this Ayah: So when his Lord appeared to the mountain, He made it collapse to dust (7:143) - Hammad said: "Like this." Sulaiman held his thumb over the tip of his finger on the right hand (so that only the tip of one finger was protruding) - and he [the Prophet ﷺ] said: "So the mountain fainted. 'And Musa fell down unconscious.'"
أَنَّ النَّبِيَّ ﷺ قَرَأَ هَذِهِ الآيَةَ ( فَلََمَّا تَجَلَّى رَبُّهُ لِلْجَبَلِ جَعَلَهُ دَكًّا ) قَالَ حَمَّادٌ هَكَذَا وَأَمْسَكَ سُلَيْمَانُ بِطَرَفِ إِبْهَامِهِ عَلَى أَنْمُلَةِ إِصْبَعِهِ الْيُمْنَى قَالَ فَسَاخَ الْجَبَلُ ( وخَرَّ مُوسَى صَعِقًا )
