Treasures from the Houshold of guidance.

[Mystic]

People can research and decide who is the liar.

Harun was from the people of Moses and his family, and see the translation here:

وَاجْعَلْ لِي وَزِيرًا مِنْ أَهْلِي

If both were primary meanings, then it could have easily be seen as "a minister from my people", but no one but one translator translated as such.

The time it takes meaning of people is when context clearly shows that or it's irrational or impossible to see it as family.

Have a good day liar.
