﴿ ءَاتُونِى زُبَرَ ٱلْحَدِيدِ ۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيْنَ ٱلصَّدَفَيْنِ قَالَ ٱنفُخُوا۟ ۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارًۭا قَالَ ءَاتُونِىٓ أُفْرِغْ عَلَيْهِ قِطْرًۭا ﴾

“Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it."”

(Give me pieces of iron till, when he had levelled up (the gap) between the cliffs, he said: Blow!) and so they blew into the Fire (till, when he had made it a fire) He says: when the iron became as hot as the Fire and thus melted, (he said: Bring me molten copper to pour thereon) to pour on the wall.
