Quran 18:96 from Surah Al-Kahf on Divine Marvels.
ءَاتُونِي زُبَرَ ٱلۡحَدِيدِۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيۡنَ ٱلصَّدَفَيۡنِ قَالَ ٱنفُخُواْۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارٗا قَالَ ءَاتُونِيٓ أُفۡرِغۡ عَلَيۡهِ قِطۡرٗا
English translation: Bring me sheets (of) iron until when he (had) leveled between the two cliffs he said Blow until when he made it fire he said Bring me I pour over it molten copper
Transliteration: atuni zubara al-hadidi hatta idha sawa bayna al-sadafayni qala unfukhu hatta idha ja'alahu naran qala atuni uf'righ alayhi qit'ran
