Al Kahf Ayah 96

ءَاتُونِى زُبَرَ ٱلْحَدِيدِ‌ۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيْنَ ٱلصَّدَفَيْنِ قَالَ ٱنفُخُواْ‌ۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارًا قَالَ ءَاتُونِىٓ أُفْرِغْ عَلَيْهِ قِطْرًا ٩٦ Bring me blocks of iron!” Then, when he had filled up ?the gap? between the two mountains, he ordered, “Blow!” When the iron became red hot, he said, “Bring me molten copper to pour over it.”
