My dear little Sister,
It is always refreshing to see you on the forum. You mentioned the Qur'an at the most appropriate place.
Pursuing personal, national, "vested" interests can scarcely take us to the status of Adam, the common person.
We can attain the much higher status of MU'MINS (believers from the hearts) only when we pursue the interests or benefit of all humanity regardless of race, color, ethnicity and geographical boundaries.
Paraphrased from 13:17 -The real existence on earth is of the one that benefits humanity.
