Surah Saba — Ayah 11 (34:11)
أَنِ ٱعۡمَلۡ سَٰبِغَٰتٖ وَقَدِّرۡ فِي ٱلسَّرۡدِۖ وَٱعۡمَلُواْ صَٰلِحًاۖ إِنِّي بِمَا تَعۡمَلُونَ بَصِيرٞ ١١
English translation (Saheeh International)
[Commanding him], "Make full coats of mail and calculate [precisely] the links, and work [all of you] righteousness. Indeed I, of what you do, am Seeing."
Brief commentary
O David! Make an expansive armour which will protect your soldiers from the attacks of their enemies, and make the rivets in proportion to the rings so that they are not too fine such that do not lodge in them, nor too thick such that they do not fit in them either. And do good deeds; I am watching over your actions, none of your actions are hidden from Me and I shall requite you for them.
