Surah Al-Anbya — Ayah 80 (21:80)
وَعَلَّمۡنَٰهُ صَنۡعَةَ لَبُوسٖ لَّكُمۡ لِتُحۡصِنَكُم مِّنۢ بَأۡسِكُمۡۖ فَهَلۡ أَنتُمۡ شَٰكِرُونَ ٨٠
English translation (Saheeh International)
And We taught him the fashioning of coats of armor to protect you from your [enemy in] battle. So will you then be grateful?
Brief commentary
I exclusively taught David, and not Solomon, the skill of crafting armour, so that you could protect yourselves from anyone who tried to attack you with weapons. O people! Will you then show gratitude for this blessing that I bestowed upon you?
