وَلْيَعْلَمْ and let him know
The front wa- links this to the discussion, and fused after it is the command-marker l- that turns the following present verb into a third-person order, a 'let him...' exhortation. That l- also clips the verb into the jussive form. So the word builds 'and let him know', a directive aimed at the dutiful one.

عَلَّمَ الْإِنسَانَ مَا لَمْ يَعْلَمْ
He taught man what he did not know.
يَعْلَمْ know
This present-shaped verb sits in its clipped jussive form because of the negator just before it, which is what gives it past meaning, 'did not know'; its 'he' subject is folded in. The shortened ending is the listener's cue that the special negator is at work.
