Dawud and Sulayman and the Signs which They were given; the Story of the People whose Sheep pastured at Night in the Field

Abu Ishaq narrated from Murrah from Ibn Mas`ud: "That crop was grapes, bunches of which were dangling." This was also the view of Shurayh. Ibn `Abbas said: "Nafash means grazing." Shurayh, Az-Zuhri and Qatadah said: "Nafash only happens at night." Qatadah added, "and Al-Haml is grazing during the day."

وَدَاوُودَ وَسُلَيْمَـنَ إِذْ يَحْكُمَانِ فِى الْحَرْثِ إِذْ نَفَشَتْ فِيهِ غَنَمُ الْقَوْمِ

The art of making armor was granted to Sayyidna Dawud (علیہ السلام) by Allah Ta` ala

وَعَلَّمْنَاهُ صَنْعَةَ لَبُوسٍ لَّكُمْ (And We taught him making of armor as dress for you - 21:80) Lexically, the word لَبُوسٍ is used for anything which is worn in the neck for protection. Here it is used for armor which is used in battle for protection against enemy. In another verse Allah Ta` ala says وَأَلَنَّا لَهُ الْحَدِيدَ that is 'We softened for him iron'- 34:10). This means that either the iron used to become soft like wax in Sayyidna Dawud (علیہ السلام) hands or he was taught to heat it up to make it soft and then mould it, a practice which is used in the foundries today.
