Two people work for a living. One earns honestly, meets obligations, and respects the rights of others. Another measures all success by gaining wealth and status, even at the expense of relationships. The problem is not honest work but uncontrolled attachment.
وَازْهَدْ فِيمَا عِنْدَ النَّاسِ also teaches respect for others’ possessions and independence from repeated demands on them. Constantly expecting access to another person’s property can damage goodwill.
The two clauses يُحِبَّكَ اللَّهُ and يُحِبَّكَ النَّاسُ use similar verbal structures; changing the subject highlights the two distinct relationships.
