34:11

أَنِ ٱعۡمَلۡ سَٰبِغَٰتٖ وَقَدِّرۡ فِي ٱلسَّرۡدِۖ وَٱعۡمَلُواْ صَٰلِحًاۖ إِنِّي بِمَا تَعۡمَلُونَ بَصِيرٞ ١١

Ani'mal sābighātin waqaddir fis-sardi wa'malū sālihan innī bimā ta'malūna basīr

[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."
