ءَاتُونِى زُبَرَ ٱلْحَدِيدِ ۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيْنَ ٱلصَّدَفَيْنِ قَالَ ٱنفُخُوا۟ ۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارًا قَالَ ءَاتُونِىٓ أُفْرِغْ عَلَيْهِ قِطْرًا ۝٩٦

18:96 Give me pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon.
