Al-Anbiya' - 21:80

وَعَلَّمْنَاهُ صَنْعَةَ لَبُوسٍ لَّكُمْ لِتُحْصِنَكُم مِّن بَأْسِكُمْ فَهَلْ أَنتُمْ شَاكِرُونَ
[21:80]
And We taught him the making of coats of mail for you, that they might protect you in your wars; will you then be grateful?
It was We Who taught him the making of coats of mail for your benefit, to guard you from each other's violence: will ye then be grateful?
And We taught him the art of making garments (of mail) to protect you in your daring. Are ye then thankful?
